Choosing between a dedicated Canon telephoto lens and a bolt-on wide/macro adapter isn't an apples-to-apples decision. The Canon EF 75-300mm f/4-5.6 Telephoto Lens is a complete EF-mount zoom lens, while the Ultra Wide Angle with Macro is an auxiliary optic that mounts over a lens with a 72mm front thread. At the listed prices, the telephoto zoom is $94.93 and the ultra-wide adapter is $151.99, a $57.06 spread before you think about what each one does.
Quick verdict
If you need a stand-alone telephoto lens for a Canon EF body, the Canon EF 75-300mm f/4-5.6 is the straightforward pick. If you already have a compatible 72mm-front-thread lens and want extreme wide/fisheye and macro options from one accessory, the Ultra Wide Angle with Macro is the more flexible add-on.

Where each product wins
The Canon telephoto zoom wins for anyone who wants actual reach: a 75-300mm zoom range, f/4.0-5.6 maximum aperture, and auto plus manual focus. It is the only true telephoto lens in this pairing.
The Ultra Wide Angle with Macro wins for creativity: it adds ultra-wide/fisheye coverage and a macro attachment to a lens with a 72mm front thread. It is new and offers fixed/prime wide-angle coverage, making it a different way to expand a single setup.
Canon EF 75-300mm f/4-5.6 Telephoto Lens
The Canon EF 75-300mm f/4-5.6 is a complete telephoto zoom designed for Canon EF mount. The focal length runs from 75mm to 300mm, with a maximum aperture of f/4.0-5.6 and auto plus manual focus. That makes it the obvious starting point if your bag is missing a long lens. This is an open-box unit, so it may not arrive in sealed retail packaging, but it shows excellent condition with no wear. The main limitation is at the wide end: the range starts at 75mm, so it won't cover wide-angle or macro subjects. If you want a dedicated telephoto without building your kit around a front-thread adapter, this is the one.
Ultra Wide Angle with Macro for Canon EF 28-300mm f/3.5-5.6L IS USM Lens
This is an auxiliary lens rather than a full telephoto zoom: it fits over a lens with a 72mm filter thread and adds ultra-wide/fisheye and macro effects. The bundled macro attachment is part of the setup, and the focal length is wide angle with a fixed/prime design. Auto and manual focus are supported. If you already own a Canon EF 28-300mm f/3.5-5.6L IS USM lens or another optic with a 72mm front thread, this adapter opens up extreme fisheye and close-up shots without adding a second lens to the bag. The trade-off is that it does not extend your focal length; it changes the field of view of the lens it sits on. That works best when you already have a compatible wide-front-thread lens.
Final choice by use case
If you want a telephoto zoom you can mount directly to a Canon EF body and shoot from 75mm to 300mm, go with the Canon EF 75-300mm f/4-5.6 Telephoto Lens. If you want to turn a compatible 72mm-front-thread lens into an ultra-wide/fisheye and macro solution, the Ultra Wide Angle with Macro for Canon is the more interesting route. The decision really comes down to reach vs. field-of-view creativity.
