Occasionally I'm using Retrogameboyz controller but almost always keyboard helps me to achieve much better results.
For example Zanac-Ex requires both A/B buttons to be pressed at the same time instead of SPACE on keyboard and that is super awkward. Also not a big fan of left hand cursor keys.
I use an 8bitdo M30 with joymega adapter, works really well. M30 seems to me to have the dpad a little bit more precise than the original sega six buttons joypad that it clones (which is already quite nice and I was used to it from my time with a Mega CDX). Being wireless with no need to be in front of the receiver and having no perceptible input lag (2.4GHz version, seems that the Bluetooth one has a perceptible lag) and battery lasting for long sessions, it is perfect for me.
While I loved using a keyboard as a kid, for most games a good joypad is better in my opinion, sure there are exceptions, but in general M30 is my choice most of the time.
I'd like to get one of those Panasonic pads, just for the OG nature of it, but not sure it's worth $60 they go for on eBay. So, it's one of those things I keep thinking I'll get later.
I use the keyboard, although my emulation days are difficult with an IBM Model M keyboard.
I have some rewired NES Hypershot controllers rather than bashing the Right hand cursor key on my HBFX1DJ. They work very well
Still have my suzo arcade turbo from +/-37 years ago, works fine, some games i used to play with keyboard, but use the suzo exlusive now. also i use the arcade turbo with M.A.M.E. on the old two button games.
I use two Sega Megadrive controllers via JoyMega Adapters. My son told me prefers those over the Panasonic MSX controller he used at the Nijmegen fair last year so I have given up looking for those.
