Ok here is my analysis if anyone cares.
BB's ACP is better for newbie tech dorks like myself. Simple ACP and of course not as much design ability as XF.
Uploading mods is 1000 times better as its all done with one click of the mouse through the ACP. No uploading to server crap. It's all done for you. < this I LOVE!
Mod-add ons Community is fair, better than here at the moment.
Smilie system compared to XF is a lot better, bulk uploads, catagories, and so forth. I'm sure Shelley would like this too. LOL
Portal system is very good and stable. Very easy to add block with one click of a button.
Adding nav links is great with one click of the mouse to add to footer or header-standard feature
Installed mod page is well laid out.
Template page is well laid out with the usual functions such as search template so on...
Language page is well laid out...
There is virtually no forum drama that I can see after translation.
The software itself is very German, meaning it's precise in terms of what it does and doesn't do. Sometimes less is really a lot more.
And there is the ability to add unlimited CSS also. I just don't know CSS so.....
The a negatives of BB aren't so bad yet but I'm hestitant in canning XF just yet.
It's a German company, thus pruducts and support are primarily German with a few English speaking moderators that are ok. The support issue is something I'm a little worried about.
And I don't yet understand how to add my header in BB.
As far as the look and feel... I was turned off by the look at first but realized all of that can be changed.
As you know, I love XF and I'm a fan but there are problems and I'm not sure if the product is for me anymore but I'm gonna keep trying by using the mod importer above and a few other things.
I would give BB an edge over XF with mods,
mod uploading, smiley ability and much much easier control panel.
I would give XF over BB for design ability and support. Support is critical to me.
What is really turning me off of XF is mod uploading and the contined forum drama.
As far as the code... I couldn't tell you about that as I just want to point and click and have things work. Could care less about code as long as things work ok.
