Noticed that I am experiencing a lot of cramps due to Zelda: ToTK so I researched for alternatives. Turns out the Split Pad Pro is the most recommended Joycon alternative in handheld mode, if you do not care about Gyro/Rumble and Amiibo. This is after considerations for Binkbok/Doyoky/Nyxi

Great prices. I have the Pro and Compact and personally much prefer the Compact as it's less chunky. If you have massive hands the Pro might be better.
