I think 'best' is quite subjective in terms of what you're actually after. Loopong capabilties? Loads of effects? Something geared more towards a certain type of playing?

A lot of buyers guides tend to recommend the larger pedals when it comes to multi efects tbh I'm not osld on that though. For instance guides like this : https://guitaarr.com/pedals/best-multi-effects-pedals-buyers-guide/ go straight for the Boss ME-80, which is great if you're a gigging guitarist but not ideal for the bedroom player...

Personally I'd recommend either the digitech element XP or the Line 6 POD, two nice pedals that are at a good price and won't be too big to clog up your pedalboard.....
