My Saga opinion...
Overall, it was a 50/50 line at best I'd say... Improvements made were marred by many mistakes made. Quality was all over the board. Availability was, pretty much, the only 100% plus because I have pretty well found everything except that last wave, which Paul Mundheim shared his extras with me so other than doubles for customs I'm cool on them.
I even saw the dreaded Ephant Mon twice... That's twice more than some did though.
I feel Clone Wars was tougher to find, as there were figures in that series I saw not once, some I only saw one time and one of (SA Clone) and some which I saw twice or so but flew off the shelves quickly (2nd wave). THAT is a line that could do with a 4th series or more I think.
Saga though had lots of goodness, especially in the latter end here... Jedi Luke, Dengar, Antilles, Dodonna, TIE Pilot, "Dutch", etc... I mean, who'd have thought we'd get all 3 Rebel Generals in one figure line, and actually within 6 months of each other or so? WOw!
There WERE some other figures I never saw... I never saw Palp's figure, and the McTrooper. I blame that one on Retail 100% as they did their usual moronic ooverordering at the build-up to X-Mas and that wave just got screwed...
But while Saga had the hits I mentioned above, they also leaked out crap like the Hoth Rebel Soldier, and pretty much 50% (and that's being lenient) of the figures from April 23rd '02 on there till the Hoth Han and TRD Luke/Vader supposedly marked the end of Action Features...
If you're talking percentages then, I'd say POTJ was superior to Saga. They were a much shorter line though, and much more comparable to just the tail-end of Saga.
OTC cards should've started last year... That's really what I'm thinking right now.

We could forget Saga and have had these dreamy new card figures then for all those kick-ass figures from Saga's demise.
