Hi. You will never find a $5 game in CT. $10 on the weekdays if you are lucky, strictly $25 on the weekends.
I spread $25-$300 in both casinos with no heat. Unlike AC both casinos have LSR which is a very powerful rule for a big spreader.
Mohegan Sun: "Earth Casino" 6 decks, 1-2.5 penetration, very variable. One quirky rule- no split 10 value cards. Pit is very friendly, dealers joke with players about counting, nice atmosphere. Also some full pay 9/6 VP machines ($5) for cover play. CSM's on about half the tables... "Sky Casino" - 8 decks, 1.5-2.5 pen, some tables are 12-spot meaning even at a full table you can still play 2 hands. A few CSM. Same rules and friendliness as above. Comps can be used for gas in the reservation gas station (makes them good as cash).
Foxwoods: huge number of tables, sometimes lower limits than Mohegan. Strictly 8D, 1-1.5 pen, same rules as above (S17, LSR, DOA, DAS) but you can split anything. Pit is AC trained so they are pricks. Comps build up pretty fast but can be used for food & lodging only. No CSM. Cheaters are present and I even saw a cheating counter once.
So if you can get to CT there is no reason at all to go to AC; better rules, better pen.
