# Security First CU vs PlainsCapital Mobile Banking

The clearest difference is review sentiment: PlainsCapital Mobile Banking at 85% against Security First CU's 14%. Security First CU's advantage is rating (4.8 vs 3.5) and ratings volume (1.9K vs 8). On price, update cadence, ads and in-app purchases there is nothing between them.

Security First CU holds the better App Store score, 4.8 against 3.5.
