Hmmm interesting... try each. I think we've established they're both pro-level. Given that famously Warwick ripped their Streamer line from Spector early on... So it's about tone and playability rather than aesthetics. For me, I love the Warwick barky tone but I'm not so familiar with the Spector counterpart but the few I've tried sounded good.
As life moves on, I'm increasingly convinced that it's all about playability for you. Aesthetics and tone are secondary as you can wang-on a Darkglass and get instant grit-o-tone from any bass and you don't see a bass when it's strapped to you.
