There are a lot of factors involved in running rigging, lines, hardware, and all things involved in boating. There are specialists that make over $100/hour to help you with this. I'd suggest getting some books on boat maintenance and asking questions here before making your purchases. Part of the problem is asking the right question at the store to get the right answer. The next problem in getting good service is finding the right person to ask it to. The chandlery may have a bunch of knowledgable sailors or one or none. Taking purchasing advice from a powerboater that overheard the stores sailor sell a halyard once..........you are probably going to get bad advice. Find the sailors in the shop and seek them out when you need help.
As long as it fits the sheaves you should be good, but for future reference there is no need to pay a premium for high tech lines for a low tech day sailor. I personally prefer a stouter line that is easier to handle, especially on the main and jib sheets where you will be handling them all day.
