The only advice I can give, as a parent with young kids, is regardless of what you go for, to make certain you let the kids help you be a part of using the stove.
I have seen others with kid gates that end up with kids poking at the stove through the gate, throwing toys in this area, etc, etc, all because it was the "forbidden fruit" and they had to get in there somehow. It is an awesome thing, and they are curious.
To avoid this, once even just barely able, let them help you by asking them to be your helper and hand you kindling, newspaper for starting a fire, bringing them with you when it's time to check on the stove to decide if you need to turn the air down yet, ask them to hand you the shovel to clean out ashes, the broom, etc, even make a point of getting in front of the fire to read their night time book. All of this will let them be involved with the operation and helps to keep them from learning things the hard way. At the same time, make sure it's CLEAR what they can't do.
Long story short, the impression I gave on my first born made his first word be "hot". Temperature was our first conversations for a period of time that seemed endless! But, we avoided injuries and he played in the area of the stove frequently.
With 1 kid, this was easy, he knew the boundaries and played near but never went close unless it was time where we'd involve him. Once kid 2 arrived, I knew when he got to age we'd have to worry about them forgetting the rules as they were in play together, in a way that either kid on their own would not, and as such, I put up 2 of the 3-fold fireplace gates. In 6 years, only once did the gates get knocked over, and I had 2 boys come find me when it happened, both with heads down and trying to explain what went wrong.
Point is, knowledge is power, yet kids will be kids. Protect them by teaching them, and throw something up as a buffer just in case the being a kid part takes over for that 1/2 second and gives them a bit of a buffer. But in the end, the best gate won't keep an inquiring mind protected if you don't fulfill that inquiry by engaging them in the process.
Good luck,
