You could make this distinction if you like.
A more normal pattern is that third party executables/packages go
in /usr/local or /opt depending on style, on the premise that you
are installing them for all users of the computer to access.
If you are installing a third party exeutable/package only for
yourself (for example, experimental or insufficiently tested software
for some special purpose) you would install it in a directory inside
your own home directory (such as the "bin" you propose).
If you are doing that, it would be sensible to do as you suggested
and have a "bin" for third party stuff and a "mybin" for your own
stuff. Just mention both of them in your $PATH in whichever order suits
your own policy.
My personal habit on machine I alone administer is to install third
party packages in /opt, for example: /opt/mutt-1.5.21 for version
1.5.21 of mutt. Inside that directory there will be a "bin" with the "mutt"
executable and an assortment of other directories with manual entries, etc.
Then to present access to it to all users I would go to /usr/local/bin
(the "global" third party "bin" directory where people expect to find "extra" software)
ln -s /opt/mutt-1.5.21/bin/mutt mutt-1.5.21
ln -s /opt/mutt-1.5.21/bin/mutt mutt
This makes two names: "mutt" as the default version of mutt that
people get when they just type "mutt", and "mutt-1.5.21" as a name
people can type to run that specific version of mutt.
Later, one can install mutt version 1.5.22 in a similar fashion in /opt/mutt-1.5.22
and make just the "mutt-1.5.22" name in /usr/local/bin (the first "ln -s" above).
If you then decide that 1.5.22 is good (and better), then change the "default" mutt
ln -s /opt/mutt-1.5.22/bin/mutt mutt
This gives you flexibility to install multiple versions of software
and to pick and choose between them later.
It presumes that "/usr/local/bin" is in the $PATH, of course.
