Youve hit on the biggest problem today with analogue and that is making valid comparisons between different components. Unfortunately I dont experience with the two you specifically reference. I have owned both a VPI and a Basis table so I can offer that up even though its not really a fair comparison since the two are at the opposite end of their respective product lines. I did use the same arm and cartridge in the period of overlap where I owned both tables.
I started off with a VPI HW-19 Mk IV with the stand alone motor (sama). This was my first venture into audiophile tables coming from a decidedly mid-fi Technics belt drive that was awful. The VPI didnt solve one of the main problems I had and that was isolation from the springy wood floors in my 1928 frame house. I had to tip-toe around to avoid sending the stylus flying. The other issue I had with the VPI was the motor needed rebuilding every two or three years. VPI was great about it and never had to pay for the service but it was annoying.
When I got to the point where I was ready to upgrade I looked past the top of the line VPI TNT and went for the Basis Debut. The build quality and the suspension are in a different league. No regrets here. I know guys around town that also have various Basis tables that range from a highly tweaked 1400 to vacuum Debuts. They all have the same superlative build quality and have recommended them to friends looking for a table.
That said, there are other interesting alternatives in todays market that should be considered. The Raven is good if you dont need the isolation the suspension can provide as is the Galibier which would be my top choice in a non-suspended table. The SOTA is also good choice in the suspended category even though they have flown well below the radar for the last few years.
The bottom line is that there is no definitive answer to your question. Even if someone had evaluated both tables in their own system, ascertained the differences and came to a conclusion, theres no guarantee that you would come to the same conclusion. Theres too much personal preference/bias in the process. Same holds true for the reviews you read in the audio rags.
