Bump stops

Hi there, I'm changing my shock absorbers for something better and more suited to my springs. The old bump stops are ruined so I need new ones, I'm looking at the powerflex poly ones but they're universal not specific. After doing some digging I've found that some people use the Ibiza FR bump stops instead, just wondering which would fit better and do the job better in terms of experiences you've had. Feedback for the front and rear would be great.
Thanks
