(Apologies in advance for a lengthy post.)
I'm on the opposite side of the coin from @el murdoque, but I'll also add that this is all 100% a matter of personal taste. What works for one person may not work for another, and vice versa.
@DCErik - it does sound like the Stomp would be more than you need, but this is Talkbass... "Why not" and "Because I can" are the normal sentiments around here, right?

May as well at least give it a try if you can, right? Is there a local music shop around you that carries them?
Having owned both Zoom* and Helix multi-fx pedals (among others), my personal experience is that the models in the Helix line are of far higher quality than the Zoom products I've owned. Not saying Zoom models are "bad," but Line 6 puts a serious amount of time into deconstructing whatever they're modeling. Hit up Youtube for real world vs Helix model comparisons, and I think there's also an interview or two with Line 6 where they talk about their process for building models.
While I'm fortunate to have some pretty amazing standalone pedals, some of my all-time fav effects have
still been from within the Stomp.
My hybrid board incorporates several standalone pedals with the Stomp, but I'm actually quite happy gigging just the Stomp because I can just throw it in the front pocket of my gig bag. I do have a standalone compressor at the beginning of my board, but that's "because I can" (aka I have the board space), not because the comps in the Helix are bad. And I actually run a second comp within the Stomp. Comp 1 is to go into my synths, but Comp 2 becomes my main when I'm gigging just the Stomp.
Since my Stomp is also my practice rig at home, I bought a second to have as a backup that I can also just leave on my desk, rather than having to pull out the pedalboard every time I want to play, which also then doubles as my "grab-n-go board" when I don't need/want my full board. It's nice having all the toys, but the simplicity of just the Stomp is also great.
There is indeed a learning curve with the Stomp, but I personally didn't think it was a big deal. It only took me maybe a couple hours of just tinkering with the pedal to get a feel for how it works. I do prefer editing via HX Edit, but navigating/editing on the fly isn't a problem on a gig either.
