I have mostly modern (post-1996) stuff. Prototypical accuracy has never meant much to me, so I'm a toy train guy. I like postwar, but I also like new trains out of the box and I like command control. That said, I find myself enjoying LionChief, LionChief+ type locos that have much of the postwar feel (at least to this geezer) and some of the modern features such as command control, electrocouplers, digital sound etc.
The prices are actually cheaper than the cheapest postwar stuff was in the 1950s, corrected for inflation. Thus if you like postwar but want similar new and sparkling out of the box models with some modern features at a value price, in my opinion, nothing beats current LC and LC+ type locos.
If you haven't tried them, you can use the included remote (Lionchief and LC+ prior to LC + 2.0) or the smart device app, or, in the case of LC+, a traditional transformer/power supply. Not a big investment up front, compared with the high-end Legacy stuff, which has its appeal but is much pricier and more complex overall. I've bought LionChief locos from Charles Ro for under $200 recently and they come with the necessary remote. Looks a lot like postwar but not quite as heavy. Just a thought
