A few comments. When you run Vim inside Emacs, the start-up is almost instantaneous, like in a terminal. Emacs poses no overhead.

If you want to go from the Vim window to the other window, you must type C-c o, instead of C-x o. In order to return to the Vim window, you need to type C-x o, which is the Emacs command that goes to the other window. You can find this information about the term-mode in the GNU-Emacs Manual. There I learned that each character is sent directly to Vim, except for the Term escape character, normally C-c.

The GNU-Emacs Manual also says that one can send a literal C-c to the Vim by typing C-c C-c. Therefore, I can enter Vim normal mode by pressing either Esc or C-c C-c

The manual also says that C-c char is equivalent to C-x char in normal Emacs. For example, C-c o invokes the global binding of C-x o, which is normally 'other-window'. Thus if you want to go from the Vim window to the other window without using the mouse, you may type C-c o.

To make a long story short, while you are on the Vim window, all chars are bound to Vim rules, except C-c. Therefore, if you are on the Vim window, and want to send C-x char to Emacs, you must type C-c x.

By the way, I did not know that it is possible to run Vim inside Emacs. Thank you for this piece of information. As for your question, I don't know why people are not using Emacs machinery as a platform to run Vim.
