Yes, I am sure a few years from now I will "upgrade" to a "better" single speed. But I will not have any more fun than I am having right now. Cutter components are crap? Of course that are, and theY work. They are not cool with a group of snobs, but they work if you ride.
The best bike is the one you ride. Makes no difference how much you spend, just ride. No issue if the bike is flat black, 24 speed, 20 speed or single gear. The only point is "am I having fun". Am I riding this bike? Plenty of $3000 bikes gathering dust. A better value is a $300 bike you ride. Does my Cutter "suck" when compared point for point on paper with a bike that cost 5 times as much? Yes. But I paid $200 (as much as 2 tire changes on my Orbea, to my Conti's) for the bike. Big smile on my face...... hope you have one too....
