I think the Rebops have a warmer tone and take less work to find whatever sound you're looking for but the Euro LX series are more defined and take a little work with the controls to get a good sound. I'd probably go for the ReBop 5 first and if you like it get a Euro later. They don't sound totally different but ReBop are a good way to gauge whether or not you'll like a Euro. My ReBop is an older model with the Aguilar OBP-1 Pre and it sounds great.
My Euro Lx6 sounds great but the Tonepump 2-band pre is a kinda limiting (funny because my ReBop's pre is 2-band) because it's either balls to the wall loud or less than great tone, but that's probably more of a pickup deal. I had an EMG BQC pre lying around so i had my local tech swap that in. I'd just like the option of being able to make subtle changes to the otne of the bass without affecting its overall character, so i'm 99% that when i pick it up tomorrow i'll be happy.
Either way spectors are awesome basses and you really can't go wrong with either it's just a matter of how much your willing to spend, because either way the quality is fantastic.
