It really doesn't matter what you use just as long as you change it at regular intervals. Using one or the other, going back and forth between them won't do any harm whatsoever.
I have changed back and forth since I have had my vehicle (purchased with 10k on the odo) and never experienced any issues, I always bought what was on sale at the local Autzone or Advance.

It's an Old wives' tale that you can't switch back and forth. The only exception might be if the engine was originally broken in with synthetic oil (which these weren't).
Just remember, if you use 0W-30 instead, you should watch out for leakage since the oil viscosity is way thinner than standard and may leak through seals.

I would go with full synthetic for engine longevity and smoothness.

That is only partially true. If there were previous existing leaks in the engine then use of synthetic oil with aggressive cleaning additives may compound the problem and make it more noticeable. Some 0W30 oils run on the thick side (closer to a 40 in some cases) when it reaches an engines operating temperature.
Check the cST @ 100 degrees Celsius in the product specification sheets.

True. I was assuming that the car would have had heavy mileage and unknown maintenance. If the engine is in good condition then whatever you throw in should work.

I would have been using synthetic on my corolla, but when I bought the car I was able to get free oil changes for 6 years. But since it was free toyota used conv and I never went to synthetic because with 74k on it I find it's whatever now...
