There's nothing wrong with wanting to stick to original hardware, if you already have it or can afford to buy it.
Setting up a Pi or other single-board system as a dedicated retro game emulator is also an absolutely valid choice IMO. It's a fun, generally affordable little project that you can tinker with forever, e.g. changing cases and controllers, UI tweaks, ROM file organization, per-game settings optimization. But I don't think that it's ever been the "best" emulation option for anyone who didn't already have their heart set on "doing something fun and interesting with a Pi".
The smartphone you already have, dedicated retro gaming handhelds, Android TV boxes or sticks, and cheap/secondhand/already-owned PCs (desktop, notebook, or kiosk) all arguably match or exceed the performance and value-for-money of any Pi-based system.
Yet in any thread where someone new to emulation is asking for advice, there's always a flock of folks who suggest getting a Pi like it's the only game in town. It honestly baffles me a little. Especially because almost all of them are just running a pretty frontend over Retroarch, and Retroarch is available for virtually every modern consumer computing platform (and so are a lot of pretty frontends, if that's a selling point).
For context, I've got a dozen or so retro systems, but I prefer to emulate as much as possible.
If you or anyone else is interested in playing more, I recommend:
I played a little of Silent Hill: Homecoming but got tired of it about 1/3 of the way through (I guess). I also bought Silent Hill: Downpour but gave up on that even more quickly. I don't recommend either of them. Things introduced in the earlier games for specific psychological reasons related to the plot - especially sexy monster nurses and Pyramid Head - tend to be regurgitated in the later games for no real reason other than "Silent Hill", which removes their impact completely.
