I highly recommend giving Kirby a look. He has answers to Ganon's weaknesses: he can escape pressure, he is quick up close, he is harder to gimp (even tho he dies earlier) and he has tools to deal with projectiles (crouching, superior aerial mobility, DASH ATTACK). But he also retains a lot of Ganon's strengths. His neutral B actually has grab armor and you can combine its quick start up with his aerial mobility to go through shields more easily. He has a solid grab game and lots of high power attacks. His reach isn't as good as Ganon's but it's still pretty good. You definitely need to spend some time getting used to his new tools, but I think all the fundamentals you develop as Ganon transfer to Kirby fairly nicely.
Also you gain some neat new advantages. Your gimping game shoots way up. You can crouch under a lot of moves. You can do some sick jab resets.
Certain match ups that are really annoying as Ganon (Ivy, ZSS, Metaknight, Link, etc) are much more bearable as Kirby and you actually get some really crazy tools in your favor. Like if you absorb Ivy, you get a fully charged solar beam. ZSS, you get her charged shot. Mario's fireballs are crazy with Kirby's superior aerial mobility.
Kirby is actually my secondary now and I can't wait to get proficient with him. I already do better with him in certain match ups with minimal practice. He's one of those characters that have a universal toolkit which works in any match up. In certain match ups though (like Yoshi), you definitely want Ganon's polarized toolkit.
