Strictly an opinion, probably the A-25's are the most subdued, therefore less fatiguing, than the others. But they don't have the detail of the Polk 7's or the early EPI 100. Those two are gems. If I had one choice only and it was available it would be the 7's with the Peerless tweeter. Every time I hear my pair they just amaze me. Even with a wimpy receiver. The Yamaha-Polk synergy is real.
Probably my favorite bargain speaker are the A series Boston Acoustics and I have had them all. Currently the 70's, 3 pairs of 150's, the 200's and 400's. I had stacked 150's with a CR2020. They sold tons of the 150's because they were impossible to beat for the money. By now they all need surrounds if they haven't been done, I had to refoam all mine but they were all nearly give-aways. They are rather easy to do, though.
Just my thoughts. I listen to a very wide variety of genres and love the one I mentioned.
