The lack of answers is probably more indicative of a lack of interest in the topic due to extensive prior discussions. Do a search and you will find many threads with opinions, debates and pics re AE bulbs. I replaced mine about 1.5 years ago with 5W models I bought off ebay (search for my thread with pics) - others have liked the mtec models (which are sold by a forum sponsor, e92). Some of the new cheap AE bulbs have too much room around the back housing of the bulb, presumably for cooling, and a couple of members have had issues with moisture/fog getting into the housing. A while back I believe Angelbright had the best quality (and brightest) AE, but they were a pricy $300 per pair.
I haven't researched this issue in over a year, so my views might be a little dated. good luck.
