Having trained and received training under 61. And having been through one 135 initial, and two 121 initials. Two 121 type ratings and an F/E rating. I don't believe in the slightest that training under 141 will make "airline training" any easier. But, to each his own....
You can make 61 mimick 141 to your hearts content. Syllabus, ground training, sims, ect. The only difference is 61 has higher times required.
