Not really.

Not in the long run anyway.

For a few days after the final I'm a bit bummed out about it but I soon get over it and it doesn't hinder my overall perception of it in hindsight. And it's only usually if my favourite actually stood a real chance at winning but lost out, eg. Tiffany (well it was certainly perceived she had a good shot anyway). When Nicola didn't win CBB19 I wasn't bothered as I'd expected her to get evicted early on anyway and knew she didn't have a very solid fanbase but just enough to get her into the final.
