I was late to the Soontir Fel train in 1.0, and when I finally got on board, I liked him much more as a fast flying gun with Targeting Computer than I did as a tank with Stealth Device. In the transition to 2.0, he lost much of his tankiness, but retained a lot of his offense thanks to his ability and tha ability to take Predator (as PTL was no longer available). The most recent wave introduced Targeting Computer, granting Fel the Lock action for a minor points increase over Predator. This also frees up his talent slot for Crack Shot. I wanted to look at when you would opt for one build vs the other, so what follows is a brief breakdown of various situations and how they favor each build.
Cost: the Predator version costs 55, the TC/Crack version costs 57. 2 points isn't much, but the bid matters for this ship, so its always something to keep in mind.
All situations assume 3 dice shots unless otherwise stated. All decimals are rounded to the nearest tenth.
Situation 1.) Target in Bullseye, no return shots against Soontir, action available for Lock (or Lock carried from previous turn).
Predator: 2.7 expected hits
TC/Crack: 2.8 expected hits, and the ability to cancel an Evade once per game.
Situation 2.) Target not in Bullseye, but another ship is, no return shots against Soontir, action available for Lock (or Lock carried from a previous turn).
Predator: 2.3 expected hits.
TC/Crack: 2.8 expected hits
Situation 3.) Target in Bullseye, both actions were used to reposition (no Lock). No return shots on Soontir.
Predator: 2.7 expected hits.
TC/Crack: 2.3 expected hits, but once per game can cancel an Evade.
Situation 4.) All actions/free tokens spent defensively, target in Bullseye
Predator: 1.9 hits
TC/Crack: 1.5 hits, once per game cancel an Evade.
Situation 5.) All actions/free tokens spent defensively, target not in Bullseye.
1.5 expected hits for both builds.
Situation 6.) All actions/free tokens spent defensively, Lock carried from previous turn, target in Bullseye.
Predator: 1.9 expected hits.
TC/Crack: 2.3 expected hits, once per game can cancel an evade.
Situation 7.) All actions/free tokens spent defensively, Lock carried from previous turn, target not in bullseye.
Predator: 1.5 expected hits.
TC/Crack: 2.3 expected hits.
Situation 8.) As situation 1.), but at Range 1.
Predator: 3.5 expected hits.
TC/Crack: 3.8 expected hits, once per game cancel an Evade.
Summary: Most situations favor the TC/Crack build. The notable exceptions are when Soontir spends his actions repositioning or for defense and has a bullseye target and no lock held from a previous turn. This isn't necessarily a rare situation, however, so depending on what your experiences are, there's reasons for either build.
