Bronica S2A was my first real MF camera. Bought it to use in wedding photography. Performed quite well, no problems. Unfortunately, somebody else wanted it too. Replaced it with a Bronica EC. It also has performed flawlessly for at least 20 years.
Had to have 6x7 so bought a GS-1 w/ AE prism. Another very good performer, easier for me to handle w/o grip. Also have a Rollei tlr, which I have not gotten along with ergonomically. My advice is to handle as many different types of MF as possible, and buy the one you feel most comfortable with. Price is a personal matter. As I said, the EC has gone a long time with no problems, in spite of its rather bazaar mirror system, You are the one who will have to balance everything out. Best of luck.
