XC 60 Engine recommendation

Hello dear Volvo community, would like to buy me a new Volvo, the lease of the old man expires. This will then become my 4th Volvo (and everyone really convinced me, I became a confessing Volvo fan), changed from the C-Class to a V-70 D5 in 2002, then the XC-90 D5 and now I have a V-70 D5. The next one is probably to become an XC 60 in R-Design, just looks great. Only which engine can you recommend me?……at the moment the T6 is my favorite……just somehow I’m a little afraid of its thirst ……. so again a D5 and then possibly with chip tuning from Heico?…Has someone already had experiences…is it worth it?…………
