Leica never gave R series to be built by Minolta. Collaborating does not equal manufacturing. And even with collaboration only R3 looked and felt pretty close to Minolta's XE. Differences were evident already between R4 and XD, then there were only R's, constantly improved, and none ever built by Minolta. R8/9 was a totally different yet short lived chapter in Leica's history.
CL is different story, one that eventually ended with Minolta solely redesigning it to CLE model, quite a different beast too.
Leica glass is a myth, especially comparing to what Canon/Nikon/Minolta were making those days. But it is true, R versions have always been well below M ones, with exception of new retail, which only contributed to complete lack of Leica SLR commercial success. At least now we can enjoy the R series for much less, imperfect as it were, yet unique.
Okay, a mix of Minolta and Leica design, but it looks like they were mostly made in Portugal, not Germany. They had to cut costs after losing so much with their Leicaflex models. The Leicaflex cost more to make than what they could sell them for.
I've had some duds with Nikon lenses; never had a dud Leica lens, so even if specific examples from Nikon may be "as good" they're not as consistent. I also prefer the feel and build quality of Leica lenses. They've always been accepted as the industry standard, not just by me - almost everyone in the know. Of course nothing is perfect, but Leica lenses tend to be more perfect than others of the same period.
Anyway, the OP asked about options so I gave my opinion. I really like my SL2 and the Leica glass that it works with. Also love my M2, but he asked about SLRs.
