Growing up as a teenager I discovered both and became a fan of both bands. Both have had success in the 80s and 90s. Even have success to this day. Both to me both have had great periods of music and a bad period of music. Both have definitely made an impact. But to me in the 80s, I think Metallica took off and Megadeth slowly took off because they were always second place to Metallica. But with the black album and countdown to extinction, both have had success and even commercial success. But the question is, who's better? I think in the 80's Metallica was better because of their music was unstoppable and hard hitting. I would say Metallica was still even strong after Cliff passed. Megadeth had some good stuff too like peace sells and rust in peace, but I still like Metallica better. In the 90's I think both music kind of declined, and the music wasn't the greatest as in I only like a few songs on Youthanasia and I like most of Cryptic Writing, but hated risk, system has failed, and the world needs a hero. I did like the Black album but only liked certain off load and reload like Fuel, King Nothing, and Fixxer. I did like Garage Inc, and I disappear. 

I thought in the 2000 both were still somewhat strong. I think Megadeth was to me starting to become better live, and Metallica was starting still good, but Hetfield voice did change again. But Metallica came back in 2003 hot, fast and hungry. But lost it in 2004. I did only like, like 4 songs off saint anger. I think in the 2000s up till now Megadeth would slowly become the better band live. I felt Megadeth was still pretty good live and Metallica was starting to kind of sound like crap live, at least James's voice.

Megadeth next couple albums were pretty good as in united abomination and loved the songs on it. Endgame was great too. I also liked 13 and felt like this was like a countdown kind of album. Metallica did great with Death Magnetic and the songs felt like old Metallica to a point, and I really liked it. But felt like Lulu sucked and Beyond Magnetic kind of was alright at best. It was great seeing Metallica go in the hall of fame, but I think Dave should have gone in with Metallica. But maybe the hall of fame will get their head out their butts and induct Megadeth in like they did Metallica. By the late 2000s, Megadeth was the better band live. Metallica wasn't bad but James's voice really took effect on him. But Metallica overall sound is still rocking live.

The big 4 definitely was great. Great to see Anthrax and Joey reunite. That band is highly underrated and might be putting out the best of the big 4 at the moment. I feel like 80s slayer is great but their music kind of became repetitive.

I felt like Megadeth was still strong and Metallica shows weren't bad, but Hetfield voice has declined, and it didn't feel like the old Metallica. I wasn't big on super collider and couldn't get into it except for the cold sweat Thin Lizzy cover. I did like Dystopia, I enjoyed the album so much I bought the cd, and even like the latest album, The sick, the dying, and the death. The album sounded good from what I have heard. Both albums, Dystopia and the newest albums, the sick, the dying, and the death, were both not bad and felt like Megadeth is still delivering on releasing new music. Even though neither to me are special like peace sells or rust in peace.

Now Metallica, with Hardwire, I liked it a lot I bought the cd and felt like this is like old Metallica to a modern style of the band. It had a lot of great music and loved spit out of the bone a lot. I even enjoyed the Lords of summers song. I thought this is great for Metallica to release after 8 years. I did watch a few YouTube Videos and Metallica as in a band wasn't bad live and even looked strong in 2019 until right before early 2020. Now since 2020, Metallica has come back and live they aren't that great. Sometimes, James will bring it with his voice but i don't think it ever came back to how it was in 2003 or the band live up until like 1993 or 1994 live.

With the latest album of 72 seasons, I wasn't a fan. I kind of liked the title track but this album was hard to get into. I didn't think Metallica needed a new album if the album wasn't going to deliver like hardwire or even 15 years prior, with Death Magnetic. I think both are great, but Metallica has had its up and downs, but both are still great live. But Megadeth is better live.

I like both bands and still listen to both, definitely the older stuff here and there.  I think Metallica was stronger and better back in the day but has kind of lost a little bit piece of the sound of the band with age, and Megadeth still delivers. Metallica is still good and brings it live. But James vocals aren't the same. But then what do you expect. I have just about every album of Metallica and a couple albums of Megadeth, like united abominations, and countdown to extinction on CD. But to listen to both modern, both can put out great music and can still play live. I think Metallica still rocks but James's voice isn't what it used to be. Dave's voice hasn't really changed much. So, studio, Metallica. Live goes to Megadeth. Who's better to me? I got to go with Metallica. Oh Yeahh! Let me know you're thought below in the comments.
