Hair: Lucas has the salt-and-pepper foof, while Romero is rocking the old-man ponytail. Slight edge to Romero because he at least parts his hair on the correct side
Ears: Romero has gigantic ones, while Lucas's are a bit more proportional. Definitely George L here.
Eyes/Glasses: It's amazing either of them can see. Lucas's wire rims are too small for his head, though. Going with Romero even though the thick plastic frames have been out of style for decades.
Mouth/Smile: Romero has the tight lipped smirk of a man who knows ten million ways to kill you with a zombie. Lucas is showing buck teeth. Romero wins here.
Chin: Sorry, Lucas, but Romero actually has one. No contest.
Threads: Lucas tries to take this with the fancy tuxedo, but the bowtie askew ruins it. Kind of like Jar Jar Binks, bad acting, and midichlorians in the prequels, despite the fancy special effects and eminently interesting storyline. Romero is cool and confident in the tweed and buttondown. Again, Romero takes the victory.
In total, I thought it was going to be a bit more even but I've got a clear win for Romero in this throwdown.
