The A30 and A50 series are fine to be honest, plenty fast for most people. Not sure about the A10 line though

Honestly imo 200€ phones are allright, but you do get what you pay. And the A14 at least here in Germany starts at like 120€, which is substantially below 200€. So if you get it and end up comparing it to an iphone, then it most certainly will look lackluster.

I would say that the sweet spot is probably in the 300-350€ range. There you have a decent amount of selection and get some really solid phones that are good for daily drivers. Like the already mentioned pixel A series that gets you clean software and shoots some of the best pictures. Or the samsung a54/55 that gets you a nice allrounder, which still includes a headphone jack and sd-card slot.

The A series is great to be honest.

It’s the same as the S series, but for people who don’t play high end games or live stream or render videos or don’t need to record videos in a high quality that I can’t even replay on my other devices.

They’re acceptable for basic productivity but very sluggish if you’re coming from a flagship device. Get an S10 series if you’re looking for something cheap and Samsung

Samsungs come with excellent Windows support right out of the box, so if Windows is you jam it’s a good choice. Not familiar with the A14, though. Would advise against cheap Chinese brands.
