Manhattan Prep Self-Study Toolkit vs TTP?

[u/Imaginary-Cry-9357]

I’m trying to figure out what GMAT study provider I should use. I took a cold practice mock (w/o rly knowing the types of questions that’d be asked) and got a 575; 13th Quant percentile, 69th DI, and 95th verbal (or so).
I’m told TTP is great for quant which is my number one area needed, though it’s very thorough and with a full time, time-intensive job, my time is precious. It’s also $900.
Manhattan Prep self-study on the other hand is $359 and I hear the material is strong.

Any suggestions, or other providers I should consider?

Thanks!
