all depends if you like blade feel or not and how much you want to spend. The R41 (for me) is a great razor, i love it and the blade feel that comes with it, so if you love blade feel and want something cheap to test your aggression comfort levels go
for it.
If you want to spend good money, on what is in my opinion the best razor out there go for a wolfman WR2 SB in 1.25. It has a little less aggression than the R41 but it is also so very smooth, this is the pinnacle of what i have experienced, but it isnt cheap and there is a waiting list atm. Previous to that this razor was unobtainable, or at the very best close to impossible to get.
If you want something between the R41 and the wolfman you can get either a timeless 95 SB or a little more aggression an OC or a Game Changer JAWS in SS. The Timeless will set you back a fair amount of $$ and the GC can be had for $120 delivered.
@holidays suggestion of the karve is a good one, it has many base plates you can play with to get the aggression levels you like, comes in both brass and SS. I would recommend plates D and/or E for aggression.
This is all i can recommend you from personal experience, but just so you know the jump from DE89 to R41 is quite a jump. If you want a milder jump, but still a decent bump up from the DE89 the SB game changer, the .84P is also a good choice.
