Even still, air balloon is better, being completely immune to fire/ground coverage is way too good to pass up
I almost forgot about eviolite cause that's definitely a good item
The berries are still a little gimmicky for my taste, yes they can alter the outcome of a match but they're still not 100% reliable
Leftovers and life orb are the best items, they are not pokemon specific and will work on any defensive/offensive role respectfully
The choice items are role specific and sometimes poke specific, it's more of, is the poke a hit and run kind of guy
Air balloon is for offensive pokemon who happen to be weak to ground moves that will always force a switch on top of having crazy good offenses (like heatran and excadrill)
Eviolite is for pokes who can evolve, making them bulkier, this item is great, there is just a lack of good pokemon to utilize it, the only ones I've heard of are: chansey, porygon2, and dusclops
The berries are gimmicky, I explained earlier
Expert belt is only good on pokemon who rely on SE hits for damage, like starmie and electivire, it does hide a choice item but it's not reliable
Everything else is very pokemon specific
