Considering this was posted in the salt forum, and this is no doubt a sub surface line, there's really not many scenarios where one would want to fish a leader long enough where the loop is ever really entering the tip of the rod to cause any issues.
Same kinda goes for worrying about a loop causing any turnover or presentation issues. Just not really a concern for any of our saltwater fishing where one would be fishing sub surface.
As far as loops durability....I've never seen any issue. (With the exception of a few infamous lines that were known to fail in general). I've caught countless albacore on factory loops and have yet to have a single issue.
At the end of the day it's personal preference no doubt, but there's a big different between fishing long leaders and turning over indicators and such on stillwaters, and casting and retrieving flies for aggressive fish in the salt when it comes to these details.
