Too many to count... I have a few for most of the consoles I own, and I own quite a few of them too... @_@

3 Wii-motes, 2 classic controllers, 1 GameCube controller, 2 ps4 controllers, 1 Wii u pro controller, 1 Wii u gamepad, 1 switch pro controller, 1 set of joycons, 2 Xbox one controllers, 3 Xbox 360 controllers

I'm looking right now at 2 GameCube controllers, 4 Xbox 360's, 4 Wiimotes, 2 Wii U Gamepads, 3 Wii U Pro Controllers, 1 Xbox One Controller and 6 Joy-Cons.

generally 4 or so but it depends on platform. For older platforms I get concerned regarding only having 2 on the off chance one breaks (think like the N64), also some systems that support 4 player games make it a priority for local play to have 4.

For the Switch I have 3 or 4 depending on how you look at it, as I have the base Joycons and 2 pro controllers. I intend to get a second set of Joycons to screw around with motion "Arms" with a friend though 

total controller count would be massive though considering I enjoy a lot of older systems. Probably over 100 but honestly that's just how it goes if you get OCD about certain colors or types, I mean jesus you could hypothetically have like 20 Nintendo 64 color variants for example if you really liked that system.

My problem is I tend to get a system to play with others. If i were more single player motivated I might be content with just individuals or 2 controls 

1 PS4, 1 PS3 controller - I don't really play local multiplayer here so I don't really collect controllers. The build quality is good enough that I've yet to replace either...though the battery life on the PS4 controller is just awful.

Had a ton of Wiimotes, and two Wii Classic Controllers, but I think only two of the remotes still work. Two Wii U Pro Controllers, One Switch Pro controller. Probably will get another Switch Pro eventually...this seems like a system I'll invite guests to play pretty often.

Too lazy to think past 7th gen.

A ton.
