It seems to be variable between machines.
My A4000 is currently displaying a great Mode 31 screen, and all other modes look equally good.
My A420 (no VIDC enhancer) looks great in all modes up to 28, even via the SCART input.
My A540, on the other hand, is great in standard modes but the OSSC struggles to sync with VGA/SVGA modes on this machine, and the screen keeps flashing as the OSSC temporarily flips from a 600V mode to 586V. Oddly, it also uses a didferent input (AV3-RGBHS) than any other Arc (AV3-RGBHV).
Screen geometry needs to be adjusted in the Advanced Timing section for best results. Vintage Macs need different timing to Acorns for best results. Thankfully these custom settings can be saved.
As for Mode 7 on a Beeb, it’s gorgeous on my Master.
Edit: I have my monitortype set to multisync, not VGA/SVGA
