After years of experience and using most every registrar under the sun we most often use Moniker and have been doing that for several years. They have an excellent control panel which is also easy to use and comprehensive. Deep discount pricing vs the high regular prices shown on the site is readily available if you ask. However, If you need good 24x7 phone support GoDaddy (who I also use a little) may be best for that.
