Please let me preface this with some words that I hope will assuage your ego.
I carried a copy of CUCM aboard a nuclear submarine for twenty years. The initial slew of good card magic I learned was from two sources, Stars of Magic and CUCM. I own every book you've written on card magic. (Ok all but two volumes they're just too expensive on eBay this week, but I'm looking.)
I don't think anyone compares to you in the sheer quantity of great magic you've authored. Some publisher that runs a magic magazine website may approach you, but that's it.
I am one of your biggest fans. No one speaks ill of Harry Lorayne in my presence because, for me, you were the biggest influence on the card magic I learned thirty-five years ago. My working bag-o-card tricks is still very heavily dependant on your writings. I have seen you work, in person and on video. I'd rather go to your lecture than any other card worker, because I think you're a great lecturer.
Now, for what it is worth, my list of the greatest card magicians, that I've seen work.
#1 Allan Ackerman. Hands down, he has the finest, most diverse techniques I've ever seen. I think his knowledge is encyclopedic and he will fool the living snot out of anyone he chooses to fool, with a card effect. I have heard really foolish, arrogant people who may not have seen Allan perform recently, make disparaging comments about his ability to present. If this were another forum, I'd profanely disagree. He is a modern marvel of raw card finesse coupled with totally disarming and flawless presentation skills.
#2 Rene Levand - I was a very young sailor and had the duty. One of my shipmates came running into the maneuvering area, where I was on watch. He said, in a flurry of words, "Ohmygod . . .Kenttheresamagician intown you gottagoseehim, I relieve you! I was spirited away to a club.
I got there just in time for the show to start. I didn't understand the language the nice man was speaking, but I could follow. He did an oil and water routine that fooled me. He did a small version of the cups and balls that floored me, but . . . halfway through the show, I said under my breath, "That guy only has one arm!!!" Nothing in my life will ever top that single magical event. Plus I got out of duty!!!
#3 Ed Marlo - I got to hang out at some restaurant in Chicago in 1978. I spoke seven words to him and stayed as invisible as I could in my dress blues. He did things with a deck of cards that were not of this earth.
The numbers are not in order of significance.
Harry you are a great magician. Compared to the three above . . .
You're a crumpler.
