Definitely still a thrill.
Most of my flying is in WT or WTP on my own. So when I get a bump to Club I'm thrilled.
First, for me, is worth it on Avios (preferably off-peak to save). It's not that many hundreds (or thousands) of pounds 'better' than Club to pay out of pocket IMO, but as the tax is the same from CW to F there's no cash difference.
When travelling with a partner it adds to the fun too - from the CCR lounge to the flight itself.
Go for it. Or do First outbound, Club back, save some Avios and see the difference first hand.
