Question of user experience with IBKR

I am getting more irritated with fidelity lately and was considering IBKR specifically for its very low margin cost. I was curious how the user experience was for people who made this switch or use it in general. I am still researching if lite or pro would be right for me on this account as well. I do mostly selling cc's and csp's, dividend stocks, and some option trading (a few a month when i see an opportunity). I also have my stocks I hold for growth as well but I doubt the experience will be much different on IBKR for that. By experience I mean trades executing on time and at correct or better price and the use of their web or desktop interface. Phone trading is not a requirement for me but could be a plus.
