I have just bought a set of Uniroyal RE (manufactured somewhen in '14) for my 900 turbo in 195/60R15 - they were dirt cheap for a V-rated tyre (48€).

They're good in the wet, rather not so good in the dry. Dry handling definitely suffers, there is noticeable understeer (well, not really understeer, as in understeer if you push a car to hard and it slides straight forwards... more of a steering delay, and you have to turn the steering wheel earlier and wider than expected, though there is no sliding around whatsoever). But aquaplaning resistance is just amazing. Hit a flooded section of the road at 120km/h, and felt the water slow me down, but absolutely NO floating/skidding... just drove through. That could have ended much worse.
Last year, one guy in the german Saab club used Uniroyals on a track day: after 300 only partly wet km they were completely gone. (Guess he had expected slightly different wheather.)
So... they are absolutely great at what the advertising promises: they are the quintessential rain tyre. But they're not so good at anything else. What makes them so great in the water - high void ratio and absurd tread depth - also makes them terrible in the dry.
This is not a tyre I'd run year round if I lived near the mediteranen sea. If I lived on the british isles, on the other hand...
Vredestein Q3 can still be had in some sizes. I have these on my other Saab. They offer crisp handling (for an all season) and are very controllable at the limit; but their limit is set not very high. On a dry warm road, a Michelin ES will outperform them vastly, on a wet road, a Michelin Alpin will inspire more confidence. They're better than a Michelin alpin on dry, warm roads, though.
Biggest drawback to the Q3 is their ultrastiff sidewalls - while that makes them handle well (for an all season, that is...), ride quality is nonexistent. I have to reduce tyre pressure down to 2 bar, while I run the Michlins at 2.6 bar and the Michelin still feel more comfortable. This reduced pressure means that the Vredesteins get hotter and wear faster.
Definitely one of the more "summery" european all seasons, but still a compromise.
