If it were me I would chose PSA. If you already have the mins to upgrade then you will do so in about 6-7 months. You will spend about 2 months in training. 1.5-2 months waiting on IOE at home while getting paid. Then come off IOE with a line and upgrade in 3-4 months. If you do the TSA thing then great you get to log a little PIC time when they let you fly in the left seat but again you are scheduling's puppet on both the CA side and the FO side for a long time. You will be getting paid less over the course of your first year at TSA and not have the QOL that the contract has at PSA. Just my 2 cents.
