Superchips vs Hypertech performance chip

[Dieselly]

Hi folks. Hoping for a bit of advice from anybody who has any experience of performance chips. I've decided to invest in fitting one to my Honda Accord and I have been trawling the net doing my research about performance chips for sale online. I read an article that suggested it is better to stick with specialist manufacturers such as Superchips and Hypertech. I've looked at a few reviews about both but would love to hear any first hand accounts or experiences anybody on here may have of either brand. Any preference? Pros and cons? Thanks in advance for anybody who could share an opinion or offer any advice.
