Hardware Synths: Oberheim Ob-Xa or Prophet

Hi everyone,
Quick question on hardware synths. I am going to buy my first hardware synth, and I was pretty set on the new Prophet, but then I read about the Oberhiem OB-XA and I don't know which to get.

I want to use it to play stuff live and also learn / use for sound design like with Syntorial. I was about to buy the Prophet,

in either 5 or 10 voice versions, but I actually think the new Oberheim might be better. It's used on more songs that I know.

When reading the comments about it I saw:

This is a $5000 modern synth with only ONE lfo and two egs???? I get that it's based on the OBX but a lot has changed since then and some additional modern features sure would have been nice. Even the OB8 had three LFOs and they're claiming the OBX8 can also duplicate those sounds. I guess it can duplicate the more simple presets using only one lfo. Basically there are people that worship that Oberheim brass sound that think this is the greatest thing to be released. Then there are people that like making their own patches and like more complex and/or versatile synthesizers. I was so surprised by these primitive specs that I thought they had to be wrong and I have been looking for an update ever since. Nope.

But both only have one LFO and I am also surprised that neither has a sine wave oscillator, but maybe that is less common? I am also not sure of what the problem with only one LFO is, but I'd be interested in your opinions on which to get.
Thanks
