Thanks for getting in touch with me! Both choruses will do what you want them to. The Orbital Modulator is vastly more variable and includes flangers, resonator flangers, phasers, and tremolo in addition to various chorus options. It's also programmable, has an expression pedal input, and can be controlled by the Source Audio Hot Hand 3. It's completely digital, which is interpreted by some as a negative, but it actually sounds amazingly analog. And in the context of playing in a band, you'd be hard pressed to tell a big difference between analog and digital. The Source Audio guys are very smart and have dealt with the digital vs. analog scenario correctly.
The Bass Boost Chorus is an excellent completely analog pedal that has a very rich '70s sound and a high degree of tweakability (yep, I got spell-checked on that word,) that will help you get that one chorus sound you might be looking for. It's got blend from 100% dry to 100% wet, detuning capability, speed and depth, and a multi-voice control that further modifies the chorusing.
So, they kinda reside on opposite ends of the spectrum: totally digital and programmable, totally analog. I like both and have used both. If you are just starting your search, it might be a good idea to get the Orbital Modulator just so you have a range of different types of modulation to experiment with. You may find that a flanger or phaser better suits you, in which case, you can look for a better pedal option later. However, if you want a great analog pedal, the Tech 21 is a great choice, but there are plenty of other chorus pedals in that realm that could be up for discussion.
I offer a 60 day trial period on any pedal you buy. So, if you can't make nice with certain effect, you can return it for full refund or credit toward a different pedal. Of course, it does have to be return in re-sellable as new condition, but I haven't run into a situation yet where a return has failed in that regard.
