That's extremely vague. If you and your neighbor have different goals for yalls operations then yall will want different things out of yalls cattle.
I'll give a good example. My family use to have red and grey Brahmans. When I was young they sold all of them and went to Beefmasters. The Brahmans got pretty wild to the extent they were literally having them chase them up the chute and in to the trailer at the end to haul them out.
When I went to buy some grey Brahmans for myself and the people I work for I had to listen to all the old stories from my dad. Basically the same thing like you heard... the didn't work for us so they won't work for you.
Fast forward and we are having great luck with the Brahmans. I just sold a Brahman bull that I loaded in the trailer with a feed buck and no chute. With our replacement heifers I can stand outside the chute and call them and they will all come through the pens, down the chute, and stand in front of me waiting for cubes.
My family created their own problems with the Brahmans by not interacting with them enough and doing it in a negative way, when they did.
Although it's good to talk to your neighbors to find out why they had problems, so you can learn from them, their problems may or may not be your problems.
