Must you make a hard choice between Adobe, Corel, Xara, Affinity, etc.

Hi Everybody,

Do you really have to make a hard choice between Adobe, Corel, Xara, Affinity, etc. for a draw application.
I only use DRAW a few times a  month so I'm just wondering.  However, I use both PhotoPaint and Photoshop on a daily basis. 
I use an older version (CS 5) of Photoshop so no renting.  Admittedly, I would prefer all tools in just one application but why fight City Hall.

You can get fairly recent versions at reasonable prices on eBay.  I bought Adobe Acrobat Pro XI for $125.

 Can the same be done for a draw vector program.
