I really like the ME-50b, I've had one for years and years, the sounds are largely excellent and is laid out in a more analogue way as opposed to screens and menus etc.
That said, it becomes a bit of a faff when you want to use two effects that appear on the same 'pedal'. Obviously each pedal has a number of effects that you select between, but you cannot assign an effect to a different pedal. As such, it's not possible to easily switch between an Octave & an Envelope filter sound without saving a custom setup, but even that can become confusing.

That's where the B3 comes into its own, you're not restricted to the preamp, dirt section, modulator section, delay section, cab sim, but you can have three modulation effects or three delay effects if you want them.
