Continuing a melee upside-down Expert playthrough:
-Hive Five is pretty good against skeletron, but not amazing. Feels better than blade of grass in general, didn't even use hive pack
-muramasa and volcano feel like opposites, super-fast and swipy vs slow and powerful
-skeletron is hard due to swarms of enemies on don't dig up; I had to build a sky arena. So many enemies are spawning, it's really difficult
-Night's edge is excellent against wall of flesh, fast kill time but have to dodge eye lasers close-up. Feels like good risk vs reward.
-dark lance is very cool. not as good as night's edge vs wall of flesh but pretty great overall
-WoF fight does feel easier near end due to changes; I fell behind twice and just 'bounced' forward with a big chunk of health gone instead of being slowly dragged forever
In hardmode I tried some of the buffed weapons
-palladium sword isn't half bad, decent knockback compared to Night's Edge.
-Phasesaber is still underwhelming, but cheaper cost makes it a nice, easy weapon to grab
-Hardmode ore spears feel powerful; mythril spear felt better than Night's Edge by a lot, but titanium trident only felt a little bit better than mythril spear
-chain guillotines have fabulous reach now, they were my first weapon that completely replaced night's edge. You can basically hit anything you can see; even without tuning the damage, these have gotten a lot safer to use.
-expert queen slime seems tuned better. definitely easier, but still died several times even with on-tier gear. I'm glad the baby slimes' bullets don't do horrendous damage anymore
