SOTA vs VPI (or stick with my Rega?)


I currently have a Rega Planar 3 (2016) with a Dynavector 10x5 that suits me and my record collection (mostly reggae, afrobeat, and jazz) but have been thinking about a turntable upgrade as my vinyl collection continues to expand.

Initially, I considered just a simple Groovetracer subplatter and upgraded counterweight, but am not sure if that is worthwhile. So now I've expanded the search to include a used SOTA Sapphire V or used VPI Prime/VPI Classic. I like the Rega's "PRAT" and no-nonsense design, but would be interested in getting more detail and cleaner, deeper bass out of my vinyl.

Any suggestions/advice/thoughts and alternatives welcome. THANKS!
For reference, my system consists of a Hegel H-160, Vandersteen Treos (non CT), Rega Planar 3, LFD Phonostage LE, and Dynavector 10x5.

I have a Sota Star Sapphire with an SME V arm. Love the whole thing. The vacuum hold is amazing and the speed is dead on accurate. 

But the number one selling point for me is the suspension. I can literally hit the shelf it sits on with my fist and it will not affect playback at all. This was crucial as i had it on a credenza for years, which was on our wood floors. Kids running around would cause the needle to jump all over the place. Now I could bounce a basketball next to it with no effect.
Not taking a side in this choice, but as someone who's been around a lot of Rega and VPI rigs, I'd say they sound far enough apart it's likely you will strongly prefer one to the other.  And in my opinion, the only person who can determine which side you're on is to give a decent listen to each
I own both - VPI TNT 6 and Sota Cosmos. Both are good, but for long term support VPI is probably better.
Thank you all for the input/recommendations. I do enjoy my current Rega (2016 Planar 3) and wonder if the step up to RP8 + Dynavector 20x2 will be the sweet spot. 

I had a chance to hear the VPI Prime, and did not like the sound compared to the Rega. There is a used Acoustic Signature WOW XL in the mix, but wont be able to audition it before purchasing, which concerns me. 

If anyone has experience with the WOW XL would be interested to hear your thoughts! Thanks.
