Pearl -
I started off in the Part 61 world and ended my time in civilian aviation with the Part 141 world.
In my experience I much preferred the -141 world for my training. I thought the structure of the program made it much easier to progress and to know what was expected of me on each and every flight.
Once I was in the military I realized that the program that I had been a part of closely resembled military training to include progress/standardization checks which the military called "off-wing" flights and end of stage checkrides.
All in all - much depends on ones personality and how they like to learn - or learn best regardless of their personal preferences!
Good luck in your decision.
