Suggestions on kedarkantha trek

I am planning for a kedarkantha trek on 24th/25th Jan and I am confused between which travel company to book. As of now I am considering banbanjara or thrilophilia. Both of them coming around 8k per person and providing some equipments along with this package. Has anyone travelled with them before, please suggest which one would be better option and what quality of gear they provide. Also I am staying back after trek for couple of days, so what places I should visit which will be near dehradun.
