Neither are terrible, neither are fantastic. I don't know what your budget is exactly, or where you are looking.
If I was spending extra money on a modular PSU, I probably wouldn't do it on a basic power supply, which is part of why there isn't a massive amount of entry level modular PSUs. Corsair has obviously spotted a gap, hence the CX M-series.
Personally, I'd either go basic non modular and better quality, or spend a bit more and get something that ticks both boxes.
Good ranges to consider - Rosewill Capstone M (good value, 80plus gold rated), Antec HCG-M, XFX Pro, Seasonic M12II (All 3 are very similar internally, usually 80plus Bronze rated, made by Seasonic).
