TP link stuff are pretty good. i have been using a TP link Cable router for over 2 and a half years with my wireless broadband provider. I have now gone over to plusnet Fibre and using the TP link on that. So yes they are pretty reliable.
One day I may get a all in one, but not bothered at the moment.
