What are the best URL shorteners for marketing campaigns?

I'm launching some marketing campaigns for my site and want to tidy up my links. I'm searching for the best URL shortener options that provide solid tracking and branding features, but with so many choices, it's tough to figure out which ones really offer good analytics and reliability. Ideally, I want a custom link shortener that lets me use my own domain rather than a generic one, so my links look more professional when I share them on social media, via email, or even on printed materials. Additionally, it would be great if I could create unique short URLs for each campaign and view click metrics by channel or region. Bonus points if the platform also allows QR code generation for offline promotions, as I'm starting to distribute flyers and event materials that link to specific landing pages. I'd love to hear about the tools that have worked best for others with similar marketing-focused campaigns.
