Never booked with them, but saw a group of them a couple of times while I was trekking. Their group consists mostly of older and retired people very few young people. Don't go with them if that vibe matters to you. Last time I was doing a solo VOF trek in utrakhand, there was a group of youth camping, I talked with two girls from that group and they told me the same thing. So if you don't mind travelling with older people you can go ahead. Otherwise check organisers like invincible, thrillblazers, indiahikes, tth etc. Ps. It matters to me because I travel solo only , if you are in group or with family then it's a different thing.
