Hello!
That's a nice discussion topic - like a one that can't be defitely concluded, so you can talk about it for generations...
I'd say I'm about accurracy - for me that's what modelling is about. Of course you have your Fantasy, Sci-Fi and the likes, but whatever is being done as a model, my requirement is that it should be internally consistent. Let's say it's a "paper panzer" - we'd probably all agree that it would be "wrong" to model the top of it very dirty while the tracks were squeaky clean.
Now there are those filters, pre-made washes, oils, pigments - and ads that try to tell you you just have to use 'em. I personally don't use those products - almost. Instead I try to get a period photo or two of the subject I'm modelling and duplicate the look using whatever works. For me accuracy means stay in touch with the real thing. Surprisingly it's very hard to find good colour photo showing the way the tracks of tanks in Vietnam really weathered - and if you do it turns out it depends very much on the type of soil that was present where that tank operated. It will look different in an Army tank operating on red clay, and different on a Marine tank operating along the beaches of Chu Lai.
Sometimes I also see people wanting to model something very much, but having no references to back it. That's when it's easy to make a mistake, lose the consistency, losing accuracy. It really pays to wait for those references, the models get better that way.
In the end an accurate model can be also pretty in it's own way anyhow, so that "artistic vs. accuracy" thing isn't a real conflict. So it's all about what you want to model - do you want to use Kit A or try Technique B? Or do you have a nice period photo and try to reproduce it as a dio? I think that's the difference we're talking about here.
Let me post two photos here, of my Duster, made almost "to specs" of a Vietnam Veteran who was it's TC in Khe Sanh and also supplied me with photos of the machine. Please decide for yourselves if that model is "accurate" or "artistic":
Thanks for reading and good luck with your modelling projects, have a nice day
