Well just looking at specs, the PL-750 is closer to old favourites like the Technics SL-1200 than it is to any "entry level" table. Just comparing the wow and flutter and SnR says a lot:
PL-750:
Wow and flutter: ~0.025% (lower = better)
SNR: > 78db (higher = better)
Audio Technica AT-LP120:
Wow and flutter: ~0.2%
SNR: ~50db
U-Turn Orbit Basic:
Wow and flutter: ~0.175%
SNR: ~79db
Pro-Ject Debut Carbon:
Wow and flutter: ~0.1%
SNR: ~68db
Rega RP1:
...They don't even list the specs for these!
Of those the U-Turn does slightly win in the signal-to-noise department, but all of the examples struggle to keep speed anywhere near as well as the PL-750, and in my opinion that's the more important of the two specs, since I've found that SNR numbers are rarely actually a good measurement. For example the quietest turntable I've heard in person which was completely silent during quiet passages was my ELAC Miracord 660 which has an SNR/Rumble spec of 47db - on the other hand my Debut Carbon is one of the loudest with its motor noise despite being rated at a SNR of 68db.
Going for an entry level new table is going to be more of a downgrade in my opinion. The reason to pick new is more if you don't have a working table, then there's less risk/hassle involved than buying vintage. That's why I bought my Debut Carbon - I already bought a Miracord and ran into a lot of problems with it that I've yet to fix, and so wanted something that would be less likely to have issues when it arrived to be my main table in the meantime. On top of that I just wanted something that didn't have that plastic resonant sound that my old Ion TTUSB had. Specs wise though almost ALL of the vintage tables I looked at would outperform it. If you already have a solid vintage table and it's fully working, no need to buy something new unless you can afford something higher end imo (unless you just like how it looks or something).
That's my take on it anyway - opinions will vary of course! All the turntables in the list including yours should be solid when setup great, but I'd still lean towards yours being the better turntable.
