To refurbish or not refurbish?

Tonight I put the finishing touches on refurbishing my very first Warhammer 40k model - A metal Ork warboss with big choppa. Which is also my first conversion - adding 'eavy armor and making a grenade launcher for stikkbomz.

Didn't do much, cleaned up the chipped paint, washed, highlights and then a varnish to seal it up.

I've heard some people say you shouldn't redo your old models, but keep them as examples of how you've improved over the years.

I'd rather have playable models then relics, but that's me. What is your opinion?
