>>36030085>BulletproofYou completely fuck certain pokemon out of existence and generally have a wide repitiore of things to switch in on, potentially expanding the list of things you check or counter to greater heights. It can turn potential no-go matchups like gengar into laughable wall situations, and nets you the ability to switch in on rogue focus blasts or gryo balls.
Chesnaught in particular can abuse this well since it has an option that's always punishing regardless of what they switch to short of a handful of magic bouncers, spikes.
Is it A+ tier ability wise? No. But its relevant when you have it. It's like a B-.
>Long reachYou can do everything you did before but this time without mild inconvenience. Nothing changes. For instance, you bypass a garchomps rough skin, or a volcaronas flame body. Does this achieve much in the grander scheme? No, garchomp and volcarona still do what they do.
Is it F tier ability wise? No. But its generally irrelevant when you use it. It's like a D+.
Long reach might be better if things that gave penalties for contact were better, or if fluffy was on more things.
Bulletproof gives immunites few as they are and that's always relevant.
