The cougar was great. If you are interested in snub as well as cap fights, touketsu is a nice option. In the heavier bomber side, waran is the best in my opinion
Personally my favorite is ROC it has a good core plus it handle almost like eagle.I have a baf and a xeno Roc. Trust me this monster can take down a lsc or gallic cruiser easily when u mount both snac and nova and traders dont stand a chance against it.It performs decent against fighters atleast better than any other bombers I have flown.
Really does depend on what you want to do with it. If you want something that is preforming good all-in-all, I'd go with one of the light bombers like Roc.
Depends on what style of "bombing" you have.... if you're one of those who want a "jack of all trades" the Bergelmir or the Roc are your ships. If you're more in big engagements with capitals and all that jazz, a Thor, a Waran or a dual nova SHF is, imho the best choices
