The F-14 is twin engine, 40% more plane and can fly faster. Also the F-14 was considered expensive.
My main disappointment with the F35 is that it could have been a lot cheaper with modern design technology and manufacturing. That and the software is needlessly buggy. I had a friend working on F35 at a time I was working on software quality research, when I discussed the possibility of applying the research to F35 he let me know that bugs were seen as a cash cow and he would be working on bugs on the F35 until he retires. He was right. And now we have stuff like this happening.
