Yes they hold up fine.  Racing, all aluminum radiators are more prone to cracking.  I've never had to use one, even for my small blocked S10.  It has a plastic tanked Vette radiator in it.

I have dealt with plastic radiators in European cars for the last 10 years. They seem to last at least 100K miles, if not more with proper care, just like a full metal one. They also run a 2 bar system (max about 30PSI) and run about 220 degree's. I have a plastic tanked one in my C10 with no issues, I also saved the old full brass one...... its in the garage as a spare if need be. I wouldn't worry about it at all honestly.

If you plan on yanking and jerking on the hoses a lot, then plastic might not be ideal. Otherwise, they seem to hold up just fine.
