I've only used an angled spotter at the range once and once on the target, it worked okay. When I bought my own spotter, I bought the straight because I thought it was more intuitive and faster sighting over the top to get on target at the 15x setting and then dialing up for better detail. I shot more in my younger days and while that scope still goes to the range, we use it more on a tripod at the cottage for watching other things than targets. Many times I'll have people unfamiliar with good optics looking through it and they adapt better to a straight through optic.
