Someone who buys a program because it is 3 SSDF ELO higher than another program has rocks in his/her head[1]. There is effectively no difference whatsoever when you consider that the error bar is about 60 ELO for Fritz and 80 ELO for GT. If there were some small, provable strength difference it will be roughly irrelevant. It is the features of the program which should drive the sales. By the time programs are in this range, nobody will notice the strength difference, except for Kasparov and peers. Naturally, 98 pound weaklings like us will get squashed whether we wrestle 'The Rock' or 'Triple-H' and we will get slaughtered whether we play Kasparov or Deep Junior. Sort of like a stereo with .001% THD verses .0001% THD. There is no ear on the planet that will be able to tell the difference. Or a stereo that reproduces 1HZ to 100KHz verses one that reproduces 15Hz to 25KHz. No human could tell which is which. Look at the database features and other niceties. Can you play online? Will it analyze your games for you? Do you like the appearance and features? Stuff like that is a lot more important than 3 microscopic ELO in an ocean-sized error bar (either for or against). [1] IMO-YMMV.
