Oh man, I feel some of myself in you talking (long time lurker, new poster). There are going to be a few crowds of people you will see. Those that love everything Mr. K does, and hate macross II (but love 7). There are those that only love one or two shows and hate the rest, and those in between which like/love most of the shows to differing degree's but can find something redeeming in each series.
Hopefully this won't sound like a rant, just an opinion.....Flame suit on
With that being said....Mac 7 is probably the most polarizing show there is and I am more then willing to admit that there is all of one or two episodes I care for (ep 26, and fleet of strongest women) and then a handful of scenes besides them (who doesn't like seeing Max run the death star trench?). In my opinion if one were to compile good battle scenes from the entire series, you would have trouble making your clip last an hour, and that is for a freakin Macross that is damn near 50 episodes in length! Hopefully that gives you an indication of what you will see. Lots of Basara, which sometimes I think people pretend they like him as a kind of joke....BOMBA!!! The "Movie" and OVA are not any better IMO.
If zero bothered you, which it initially did for me too until I watched a good translation, Macross 7 will more then likely have similar results but too a much greater degree. It is Macross so I have no choice but to watch it, but it is definitely like the strange uncle of the family that says inappropriate things and makes everyone feel uncomfortable.

One of the reasons I feel that Frontier is so popular is that it stays true to the original Macross feeling yet manages to update it for a modern generation. Most of the new anime conventions I could care less for (fan service, high school mecha pilots(I like to pretend it is a college) and making 14 year olds sex symbols) but the music is great, the mecha are great and the story creates drama. At a very minimum from an action perspective, Frontier won't let you down. With that being said, the whole "song energy" thing started in Mac 7 and continued in Zero is here to stay, even in Frontier, so you are going to have to get used to the idea and rationalize some plausibility into it so you can enjoy it more.
*Flame suite back on*
I also recommend Macross II. It is not series canon and the animation is a step down from DYRL even though it is newer. It is probably the second most polarizing of the Macross because Kawamori did not do it and people don't like that it is sort of a recycled DYRL; however, it does retain some of that original Macross feeling.
