The crux of it and what makes this such a personal choice is that how important each pro/con is to you is so subjective. You can absolutely make a long pro/con list for each, as you have done, and include all the points everyone else has given you. Honestly, those are fairly easy to compile at this point with just minimal research on here and elsewhere. The tough nut to crack is deciding the value of each. Every pro/con is not a 1 for 1. To me, not commuting would probably outweigh the first 20 pros put together on the other side. Some people might not care about commuting but value pay/no passengers/whatever way higher than anything. So even if one side seems to have less benefits, if one or a couple of those are worth more than all the opposing ones put together, try to figure that out. Also, being in base just about anywhere is worth a 10-20% seniority bump vs commuting somewhere else because of all the possibilities it opens up re: upgrades, what you can bid for month to month, etc. Six years is a big seniority hit, but I would argue if you are going from six years seniority at a place you commute to vs year one at a place where you are in domicile at their main base probably cuts the seniority hit down by at least half.
