resolution of davening quandry - what do you think?

So, I spoke to my rav regarding the quandry I mentioned and here is his solution. He said it is better to daven at the minyan that allows me to be there the whole time, but to work on training myself to slow down for shmoneh esrei and have kavanah. So, even though it will take some time and for a while I will daven with little kavanah, in the long run that is better.
