Older US made high quality SAE wrenches are usually pretty inexpensive and often found at garage sales, thrift stores, and pawn shops. All of my imported 19mm wrenches and sockets have been replaced with a 3/4" Proto, Mac, Matco, Snap-on, etc.
This wrench's 6-point box end is preferrable for not slipping on previously damaged fasteners, but it may be difficult to get oriented and repositioned on the fastener if it's in a tight spot. 12-point is the norm for box ends and won't strip the fastener unless it's already rounded or heavily rusted.

A 3/4-inch box-end wrench is extremely close to a 19mm wrench, essentially interchangeable for most uses, as 3/4 inch converts to 19.05mm (0.750 inches vs 0.748 inches), a difference of only about 0.02mm (2/100ths of a millimeter), making them practically the same size and often listed as equivalent in conversion charts.
Key Comparison
3/4 inch: 19.05 mm (0.750 inches)
19mm: 19.00 mm (0.748 inches)
When to Use
For most automotive/general tasks: They are very close, and a 3/4" wrench is often used for 19mm fasteners (and vice versa) without issue, especially on things like lug nuts.
For precision work: If you're working on high-precision machinery, the slight difference might matter, but for everyday jobs, they are considered interchangeable.
In short, if you're stuck and have one but not the other, go ahead and use it – it's a near-perfect match!
