R7 is neither as grippy, nor as spinny, as T05 at the elite level.
However, R7 is an easier rubber to control, and so many players (i.e. below the elite level) might be able to play spinnier shots with R7 than with T05 as they will feel more 'in control' of what they're doing, play more confident shots, and actually end up generating more spin than they would with T05.
For example, in the league that I play in, in Division 1 (which includes some high-ranked national players), the three players that have the 'spinniest' shots in the league play with R7, Joola Rhyzer 48, and Fastarc G1. We have a number of players that use T05, Dignics 05, or Dignics 09C - but they don't generate close to as much spin as those who use the aforementioned rubbers.
