Tank would be a decently stocked 75gallon.
I want good filtration, but not go above my budget I set for myself.

I Concur, and use sponge filters myself, but I always like to have something to back them up or vice-versa actually..LOLSponge filters. Cheapest and best option for that tank size.
Actually, the 304B and 404B are 98% exactly the same, just the 404B has a nice carrying handle. I have both.
As for the OP question, if you can only have 2 of the 3, go with the 304B and the AQ110.
If you can go with all 3, go for it, but shouldn’t be "necessary". One of the the main advantages is that you can always THOROUGHLY clean 1, and reasonably know that the other can hold the tank's bio needs until the recently cleaned filter catches back up in the event you may have accidentally lost too much beneficial bacteria from cleaning.
I also have a CFS700,(and a CFS14i/1200)....
If you are NEW to canisters, I do not recommend CFS canister filters, as they will generally have to be modified right out of the box, and due to their cheap plastics, are easily damaged by heavy handed inexperience tightening the lids.
YMMV....

I own 3 of these Odyssea canisters, with one going on 3 years. I didn't do a single modification......haven't had a single issue with any of my 3.
