I'd say there's definitely something wrong with that. 1500 hrs of 172 time is not appropriate for flying a transport jet into LaGuardia at night in icing. Only very specific circumstances make CFI>regional competitive.

At your phase in the career, it's about making your logbook better. (Thicker too, but mostly better.). If you get offered a job that makes your logbook better, you take it unless there's a strong reason not to.

Planesense is reputable. Planesense has reasonable QOL. Planesense will give you multi-crew, turbine, night/icing/complex airspace experience. Planesense will make you much more marketable than ASEL CFI

As for where you wil be in 12-24 months ... who knows. Get 4 seasons of flying in at PlaneSense, upgrade if you can and then start looking around.

I would bet $100 that when the sun goes supernova, 2021-2023 will stand as the all-time highpoint of airline hiring. I don't think furloughs are happening anytime soon but hiring be slower than it was. Probably a pace that allows the regionals to recover and restores the normal universe where experienced regional captains outnumber big 6 job openings. All of which to say ... make yourself a plan to get to a major at 30 & 10K hours and work backwards.
