Bryant Electric was an independent manufacturer of electrical products, founded in 1888. The grew and eventually became associated with Westinghouse, who eventually offshored much of the production and eventually sold the entire Bryant line to Hubbell in 1991. Somewhere along about this time (1994) Eaton acquired the Westinghouse electrical division that controlled the Bryant panel lines, and then immediately divested itself of the circuit breaker and panel lines to Thomas & Betts. With the ABB Ltd company acquiring the Thomas & Betts Corp, the circuit breaker and panel line was sold to Cutler-Hammer, as ABB has its own lines of circuit breakers and power distribution panels.
Long twisted and convoluted, but the C-H Bryant panel line is a decent quality product.
For the OP, if you have a decent, modern panel in your house now, buy the same brand, type, etc, for breaker commonality. It is worth spending a couple of extra bucks on, to know you don't have to try and remember which panel is which brand when you are at the store buying an additional breaker or part, and you have the option of cross switching breakers during modifications, upgrades, or emergencies.
That being said, I have a mixed panel situation, with an older Square D QO panel in the house, and a Siemens panel in the shop. Eventually the Square D panel in the house will get replaced with a new Siemens one for a number of reasons I won't bother to get into. At that time the house will get a outside disconnect, and four wire supplying the panel, and the grounds and neutrals separated. Presently the SqD has a short, bleacher seat stack of ground/neutral bar jammed up near the main breaker and no room to work, and no room to separate the neutrals and grounds.
