I use Photoshop for my minor quick things... like textures... but if you are doing branding you might want to use Illustrator because it works with vectors and can be downsized and upsized easily. btw Illustrator does cost $60 a month and is not recommended if you aren't making money off anything you use Illustrator... (Example: I work with a design company that owns several huge and expensive printers and can make stickers, signs, t-shirt designs, and window clings) If you have photoshop stick with it.. it is your best option.
