Pathfinder is skinnier, but I really don't think it's that big a difference overall. The downside is limited upgrade path if you do decide to do deeper dives. The original idea, which OP might like, was to sling the the combo bailout/dil and get the DIL off your back, but mostly I see people set it up just like a Meg and the only real difference is that it is skinnier and lacks the redundant network as well as any ability to go to a bigger scrubber canister if that is later desired. Part of the reason that it is discontinued, I believe, is that the Meg15 head is lower profile so you can use a smaller can with the same scrubber and do a mini-meg if you want. You get most of the benefits of the Pathfinder while maintaining the upgradeability. In other words, there was less need for a Pathfinder model when the head shrank with the '15 update.
FWIW, my understanding is that the Meg15 (which I have) is not discontinued nor is the Apecs system being discontinued.
There were tons of problems with the existing Apecs IV handsets and their batteries/charging system, in particular. Almost everyone I know had to get a new battery at one time or another, including me, but ultimately it's worked out fine. But, it was a huge headache and gave the A4 a bad rap (deserved).
As of DEMA, the word was ISC was working on a new Apecs handset to replace the current one. I understand it uses AAs or something disposible, like a Petrel, rather than the Lion in the current one and thus dispenses with the $80 dollar charging adapter and solves those battery QC issues. Hopefully, it won't be the ergonomic brick that the current A4 is either, but I don't know.
What I heard was the Tiburon was a gapfiller while the new Apecs handset was being developed and the Meg 15 would continue on. In the interim, ISC was stockpiling existing handset parts to support legacy A4 handsets rather than shipping more Meg15s with the current handset.
Now, I'm confident that the Tiburon is not just a "gap filler" because ISC knows darned well that folks have been asking for a "Shearwater Meg" for a long time. I'm sure it will continue on, but I don't think the 15 or the Apecs electronics are going away either. For one thing, I suspect strongly that ISC can't just substitute a Tiburon for a Meg15 on its military contracts. But, that's just speculation.
