Which is the better lighting option for an HAI system, UPB or Radio Ra2?

The bottom line is HAI supports both so the decision really comes down to other factors - you want to minimize RF in house, noise on powerlnes, look, cost, feel, breadth of device available, support, etc. Those are all things you need to consider before choosing a lighting technology. With Ra2 I believe the software is only generally available to dealers/installers and not the general public so that may be a small factor to consider.
Lastly, if you search these forums, especially the Home Automation forum you will find a plethora of information about lighting including these technologies (more so for UPB since it is more popular/widely used). User Neurorad knows alot about Ra2. And not to confuse but keep in mind there are other options like Zigbee, either like Centralite Jetstream or now any Zigbee that supports the HA profile.
Oh, and make sure your electrician puts a neutral wire in EVERY switch box!

Wanted to note that you have to differentiate basic UPB from HLC, because you will not be able to easily program a generic UPB switch to use an HLC-type setup. So if you decide to go this route, make sure you get actual HAI HLC UPB switches. You can mix and match, but as Steve mentioned for the regular UPB switches (as well as more advanced scene programming) you will need to use UpStart which is quite a bit more work, especially if you want to use an HLC-like layout in your home (which allows for nice instant status updates when switches are pressed etc).

i've been frustrated by a few aspects of UPB / HLC:
1. that there is no collision detection for use of the bus (as seen in the case where you have two UPB switches next to each other that rely on UPB links to effect their function, e.g. virtual 3-way switches; hit the paddles of the two switches one after the other, and one or both UPB messages will be lost)
2. 'popcorn' effect when you switch on one or more rooms via HLC
3. high latency of using switches to affect dimming levels via UPB links (tend to under/overshoot)
4. inaccurate state tracking with HAI-brand HLC devices (and, yes, i have checked the configuration is correct).
5. i've also had UPB devices occasionally develop corrupted programming; not sure why that happens but it's happened more than once.
it's not clear that RR2 will necessarily be better for me but based upon what i've read and heard from others, i'm expecting it will be.

I use all SA devices - I'm happy with their dimming performance (some lights I extended the default fade rate so I could have more granular control), etc.
The collision issue only comes up for me if two switches are hit at the exact same time; if they're within half a second they work fine. I've worked around this with some custom actions - instead of hitting both rockers on/off in a group, I just double-tap either of them and it causes both to act, or a whole room to go on/off.
Unfortunately I don't have any RRA experience to pull from though - so hopefully you're happy with that setup.

They're setup in the HLC scheme.
They are all SA units.
Setting them up is easy. All HLC really is is an allocation of units and links in a specific structure.
You don't have to use the default behaviors for the HLC links.
The room associations do not have to be a single physical room.
It's very flexible and reliable.
I have the phase coupler in the circuit breaker panel.
There are several good threads on this site about using non-HAI UPB switches int eh HLC mode and modifying ht ehLC link behaviors.
Here are the relevant HAI knowledge base article links.
