0b11 vs carista vs vcds

I had my  car scanners nicked when I was moving house (stupidly I left my garage open) so with my car doing some rather odd behaviour recently I need to get a new one.

I have been looking at the carista  + app

The obeleven + app 

And vcds 

I get carista - simple and pay a monthly/yearly subscription should you want to make changes or use more advanced features 

Obeleven similar to carista but you can either pay, watch adverts or long coding is free 

Vcds - one off cost it's expensive but can do everything ( more than obeleven??)

Does anyone have any experience or recommendations 

Ideally I want to get as much info to what's going on but I'm not that bothered about changes but some might be nice 

Can ob11 see dpf details? As vag dpf pro doesn't work for my engine
