It's your tank and there for your enjoyment. If you have it for any other reason you should give it up. That being said, the fish and plants you stock with are really no one's concern other than your own. I have fake plants in one tank due to the livestock wanting to eat the real ones, and tank with mixed, and a couple that are all real. No one has yet to identify which are which! I often hear people remark that I must have a bundle tied up in all those fake plants until I prove to them that most are real (which actually cost me less). I would guess that is a testament about how good fake plants are made.
Do whatever it is that works the best for you and at the same time gives you the most enjoyment. It certainly doesn't matter what anyone else thinks.
