I'll say go for VIP10. Its more stable.

I had previously upgraded from VIP10 to Advance 30, but the experience is not pleasant with 30Mbps. The speed fluctuated a lot and TM didn't bother to improve it at all. They ignored my complaints and i was told to provide proof of fluctuates, but they don't accept the screenshot of speedtest i provided, instead they wanted me to do the speedtest from a URL they provided which shown full bar speed at all time of tests (i suspect it was a simulated version speedtest by Unifi).
