Single easiest character to kill or gimp maybe if you suck at mixing up your recovery. Falco has recovery options.
Options which are fairly simple to cover if you know what to do and can react quickly. People super suck at this.
And as far as being tech-chased to death or whatever, he doesn't have a bad tech roll like CF does and he also has things like quick attacks out of techs to make punishing him slightly harder.
He dies much sooner out of those tech chase though. He gets to his legit dying/kill percent 30% earlier than almost every other character, including Jigglypuff. All top/high tiers have fast attacks out of techs, none of which should ever be coming out if you are doing your tech chasing correctly.
His physics work more to his benefit than they work to his disadvantage. IT's a double-edged sword, yes, but one edge is definitely sharper than the other. lol
Yes, they do work more to his benefit or he wouldn't be a top tier character. However, him being a glass cannon/double edged sword when you have a character like Fox with nearly all of strengths and almost none of his weaknesses is silly. With Fox existing, you should probably reconsider him for being the simplest to play (if you're disregarding tech skill stuff, which is completely ridiculous btw) especially when few people can even play him really, really well.
Also, stongers has the most entertaining FAlco ever. So unbelievably goofy. I can hear it saying
this everytime he hits/combos you and it makes me happy
Lmao yes
