So this might be hard to "say" -- and have it come out right -- I'm not picking on either car - I'm just going to be comparing the advantage or disadvantage of the two cars. Which is what you're really asking about.
IMHO both cars need to be complete re-dos if you want to make them real PT cars... So in that case - they appear to be about on equal footing... Paint doesn't count - since if you're going to do a REAL PT car - you're going to be modding just about every facet of the running gear - which means lots of hot sparks flying - which means PAINT JOB...
Complete wiring in either car - equal $$ and work
Complete interior both cars - equal $$ and work
Tires and wheels both cars - equal $$ and work
Vintage A/C both cars - equal $$ and work
Any "savings" might come from some form of reusable engine parts - block / heads / intake etc... and rear end parts... raw housing - axles - gears.
SO NOW IT COMES DOWN TO WHICH ONE
YOU WANT TO BURY YOURSELF IN.
If you just wanted to Clean them up and drive 'em -- that's a completely different assessment and you'd have to see them in person in order to do that.
Here is a piece of advice -- and lord knows I'm free with that!! LOL
I tell people that ask me. It costs the same amount of money - and in many cases MORE to do an "orphan car" - versus a "popular" car. Say some odd 60's Buick vs a 60's Mustang or Camaro... The popular cars have lots of bolt on repop parts etc... and it's a competitive market... And when you get all done and want to sell it - I'd put my money in that popular car vs the orphan car.. because the market just isn't there for the oddball stuff... So unless you have lots of money and just "want one" - then stick to the normal marketable cars... Now I'm not talking RARE collector stuff here... that's a different can of worms. BUT both of the cars you're dealing with are great candidates for projects or make overs... great body styles etc... so I'd just pick the one that make my heart go pitter patter.
Plan your work - and work your plan.
