You are aware of the potential for comparison...that in itself gives you a huge edge in avoiding it. Most folks that make this mistake don't realize the issue even exists.

If this rescue is close to you, I would suggest you get involved. Volunteer for them, make donations. Get to know them.

There are two benifits for YOU with this, and of course...anything you do to help will benifit the dogs.

First, if the rescue likes you, you obvioulsy have a much better chance of adopting...and some rescues can be VERY picky and strict about rules. Like no adopting to renters, or must have a fences in back yard, or some such.

In case you don't meet some criteria they may have, they would be much more likely to make exceptions if they know you and how serious you are.

You will also learn how the rescue operates. You will have a chance to see how they screen, house, and adopt out dogs. This IS important...as not all rescues are good at it. Some may place unsound dogs or have poor placement policies.

You don't want to be involved with a shady rescue.

You could also consider foster-to-adopt. Or just simply foster dogs until you come across "the one". This will A) free up space to allow additional dogs to be rescued and B) allow you to get to know a potential dog, and be sure he fits your lifestyle and ability before making a permanent commitment.
