Tactics Ogre does fit with Sakimoto's style, yes. With Final Fantasy Tactics he moves into much greater and more cinematic leitmotivic usage (which he carried into Final Fantasy XII with him).
I haven't listened to Tales of Phantasia that extensively, but I probably wouldn't have listed it anyway - Tales is pretty reasonably well-known, I think. Nor've I listened to Treasure Hunter G, though that is a gap I should rectify soon.
I didn't even remember the Albert Odyssey games! But you do hit the nail on the head. They're just not as memorable as the Saturn game. It's got some decent tracks but nothing that truly stands out (aside, maybe, from "The Road Walked By Heroes" off the top of my memory) the way that any of the games I listed do.
I truly hope you like Treasure of the Rudras. In my opinion, it's just as good as the other vgm masterpieces Square was turning out. It deserves a place alongside Final Fantasy VI and Chrono Trigger - it really is tha good. Hopefully Sasai will return to videogame scoring one day. Like Shiono, we've heard too little of him.
