I haven't looked in a while either (since 2015), but from my email:

UltraTax pluses:

Offers a lot more composite nonresident returns than Lacerte

Offers more state estate tax returns and state exempt org UBIT returns than Lacerte

Integration with Thomson Reuters Creative Solutions Accounting trial balance software

MD Personal Property Tax return is an available option, for a fee.

Minuses:

The printed returns look like crap compared to Lacerte

No Missing Data flagging

Only one person can be in a tax return at one time (no looking while someone else is working)

Government forms instructions are not readily available from within the program.

You have to enter the ERO PIN in every tax return

A lot of informational forms are designated as "noncalculating". Meaning, for example, you must enter taxpayer name, address and ID # umpteen times on a 5471.

Won't produce 2 gift tax returns for gift splitting from 1 file.

They don't offer a fixed price for returns of all types/all states, so it would cost us more than Lacerte.

I agree with everything Phoebe said.
