Properly tuned, AEM and Hondata should make identical power on identical setups with identical tunes. In fact, people have done just that.
Where Hondata excels over AEM is simplicity. Hondata is based off of a stock Honda ecu - and as such, parameters such as coolant temp enrichment, idle air control, air conditioning, and tons more parameters which can be quite difficult to set up, are already done for you by the best in the game - Honda Engineers themselves!
Thats just a small part of why I choose Hondata over AEM.

btw, Hondata is not tuned via a palm pilot.
To answer your question about needing a retune after you upgrade cams or a turbo... yes you need to retune... HOWEVER You'd also need to retune the AEM system as well. So if you're a big spender, go for the AEM system. If you want something that can do anything you want it to, for very limited cost, go hondata.

I looked at alot of options when building my car and the one that made the most sense for me, was Hondata. It is simple, reliable, and it gets the job done. My car is daily driven at well over 300whp everyday - no problems at all. Tuned by John at Secret Services, naturally 
It's really up to you, I'm not gonna tell you if one is better then the other - just what I use and my experience. It is a matter of deciding what features in a engine/fuel management system you want for your car and which product best fits that profile.

I looked into F.A.S.T., AEM's EMS and Hondata. I used the software for AEM's EMS and Hondata. I found Hondata to suite my needs better and John is going to do my tuning so I went with Hondata. I'm looking to put down 400WHP - 420WHP on pump gas and 465WHP - 535WHP on race gas.

this seems to be a battle between AEM and hondata. hondata is obviously more user friendly than the aem as john stated, but if youre not the one tuning it thats not even an issue. youre paying someone else with assloads of prior knowledge and tuning experience to do it for you so what does it matter if its user friendly? once the tuner is comfortable with the program thats not a factor. i like the way my car runs on hondata but personally if i could go back i would chose aem because of its adjustability and datalogging feedback(which i know is an 'option' with hondata). with aem you dont need anything besides a laptop and wideband/dyno to tune your car. everytime i change soemthing on my car i need to go thru the whole process or getting it "retuned" which i personally dont like and it seems like a waste of money because i know i can do it myself but i just lack the equipment.
john i am not knocking or questioning your tuning capabilities at all, you have done nothing but excellent work from the get go for me, but right now i am at the point where i wish i could just do all of the minor adjusting on my own, and i cant with the hondata.
for the average person that pays someone to build their car and really knows nothing about it id say hondata is the way to go mainly do to the price, which isnt even a big difference if your working with an obd2 car, but if youre looking for that ability to alter it on your own and u feel comfortable messing with your own car id say AEM. also ive seen and used the AEM before and its not something you can learn over night, it takes a lot of time and experience to know what youre doing
