What are you shooting with flash? Are you using ETTL, (or iTTL, for Nikon), or strictly manual?
How are the Altura flashes working out for you so far? If one breaks can you get it fixed?
What is it about Altura that causes you to think about replacing them, other than the name?
My YN-560's have always worked flawlessly, and I really like the newer 560-IV version with built-in trigger receivers, as well as the 560-TX transmitter. But recently I (and many others) have switched over to Godox because of the X1 trigger system and availability of bare bulb flashes and strobes that use the same trigger system for manual and TTL control, and due to the outstanding USA-based support from Cheetahstand and Adorama.
But the the Altura's are doing what you need, why spend money on replacements, particularly if it's only as a hobby. If you're using them professionally and are concerned about the name, put some gaffer's tape over the logo.
