I know I can't change your mind MM, but rather than breaking out my thesaurus and dictionary to join in this conversation let me share my experience as a collector and maybe that will give you some insight into why I now seek out stylized figures over more realistically rendered figures.
I'm a 30(+ ughh) year old collector, I have a wife, a child, a mortgage, a retirement plan and I have spent thousands on toys that capture my imagination and let me relive the nostalgia of my youth.
When I started collecting, much like you, I only wanted realistic sculpts and paints but as I continued to collect, my collection got repetitive both in sculpts and colors. I did find myself attracted to a few figures in the Marmit Monster Heaven line and about 4 years ago I added GMK Godzilla (
http://i.imgur.com/rTFDRqgl.jpg) to my collection. It was unlike any other figure i owned and i proudly displayed it right next to my brand new 25cm X-Plus GMK figure. To me it was, and is, a piece of art.
So i continued my Monster Heaven buying with Orga (because, OMG that sculpt and paint are way ahead of the Bandai) and the spectacular G2k sculpt among others and the occasional Parababy. But then i continued my GMK binge by picking up an M1 Baragon and damn. it was over. The paint job was so phenomenal I was hooked. Megaguirus, G2k, Biollante, the rest of the GMK bunch... i just couldn't say no to M1. (and people like TripMasterMunky only encourage this behavior by posting pictures of their M1s

)
I still bought realistic sculpts, but at this point in my collecting i would get a 25cm X-Plus Gigan and then most of my other realistic Gigans would make their way to storage, while the Parababy Gigan, M1 Gigan, and MH Gigan all remained displayed. Sure i had some small scale stuff (X-Plus Chess Piece, Iwakura) on display but they are just pretty ways to fill in the gaps left by all these tails (::side note:: remind me to ask about "tail management" at the G-Fest collectors forum). To me i could only have one "best" figure in terms of sculpt and paint, but with the stylized figures i could have more. They were artistic renderings, so i have an M1 an X-Plus a MH all prominently displayed and despite all being the same suit they all look so varied an unique that the collection looks better with them breaking up the flat paint of the X-Plus and Bandais.
The thing about art though, is that the beauty is in the eye of the beholder. For instance, Legion (who i have a TON of respect for as a collector) sees the Gigabrain Ghidorah as completely capturing Showa Ghidorah better than any other figure. To me, while I found a lot of nice things about the sculpt i thought it was missing the characteristic that in my mind defined Showa Ghidorah, so i (in the admitted minority/alone) thinks the stylized CCP release of Ghidorah captures the snake like necks better. In the end i just said that the Gigabrain was not for me and so i sold it. Similarly Mekagoji3k prefers Marmit VP figures over Marmit Monster Heaven figures and even though i feel the exact opposite, I am always looking forward to hear what he thinks about a particular figure (even when he's wrong... SHMA G64, i'm looking at you

)
When it comes to 3 figures that sparked this conversation, I won't be picking up any of them, but i might pick up the G54 with the train in a different paint (im thinking black and silver in high gloss.. Maybe a KaijuZoo exclusive

) if it were available.. and i would be sure to post the others here because there are people that the aesthetic appeals to in the same way i love the Toygraph Meganulon (despite him inaccurately standing on two legs..and missing two legs...)
So i'm not offended that you think what i do is a waste, I just think that in 4 years if you're still collecting you'll be picking up stylized figures as well.
