I have zero drifting issues as I use a pro controller for docked play and I treated myself to the Hori split pad pro for handheld. That thing is so darn comfy and the sticks are at one with my thumbs, sure it bulks out the Switch a bit, but I don't cramp up anymore with longer play sessions.
Hori Split pad is amazing. I now only use it when playing handheld. Kinda feels like an XBO controller in handheld mode.
