The memory footprints of Emacs and vim are virtually identical (try it!). Things like the splash screen can (and should) be disabled in Emacs.
The one situation where I find Emacs lacking in performance is for very large text files (hundreds of megabytes). And even that can be (mostly) fixed by disabling, line-number-mode and syntax highlighting if the file is larger than some threshold of your choice.
