It kinda depends on whether you watch the original Japanese version of Sonic X, or the 4Kids dub. The 4Kids version opted to change a lot of things, to the extent that even some plot details are entirely different or removed with edited scenes to suit the dub. One of these changes was Chris's characterization, which is much better in the Japanese version.
I'd probably recommend the Japanese version (with subs if necessary) for any first time watchers just to get the raw, uncensored version of events and preserving the original intention behind the portrayal of the characters.
