The SP2.3 for the 727 works great for me. Only the Autopilot is finicky when try to catch the ILS and GS, but it works about 90% of the time. Maybe better than that, now that I know how to do it.

I backed up my 727 SP2.2's on a DVD (as are ALL my payware add-ons for Flight Sim), so I still have them.

As for the 767 SP1.4 and 757 SP4.4 they work perfectly for me. The only issues I have appear if I increase the sim rate to x4 or more.
