Least amount of hassle would be the Miyoo Mini+ with DotUI installed. Reasonable price, pleasing design, simplest frontend and interface, and decent PSX performance. If you want sticks and stacked shoulder buttons for better PSX play, or enough power for PSP, your best bet might be the Retroid Pocket 2S, but I'm not familiar with emulating on Android so I'm not sure how much work it takes to get running.
Sadly with these devices even if the price and form factor are right it's always going to take some amount of effort to get them ready to play games well. But if you're satisfied with Gameboy systems and 2D consoles then the Miyoo Mini+ is the best bang for your buck and DotUI is the easiest frontend to install and use.
