I think you will find everyone's preference differs on the optimal size carried. I just got a Para2 and while I am enjoying the knife, I think this will be the largest knife I will buy that is a non-fixed blade. I personally find that a knife with a 3" blade often had the right size handle for me. I never really feel the need for a larger blade so this has kept my knives in that general vicinity of sizing. I have owned 3 Delica's so far and have loved them, I would highly recommend them as a greater first knife. Comfortable size to carry and use, no one takes notice to my knife as it isn't daunting looking, light and easy to clean, a few different configurations to select from. Good luck with your selecting your first knife, I have always found have the fun is shopping and researching.
