I see. Pardon my quick judgment, I had felt that when watching through a few Youtube demos. Hehe. Well well, gonna really seek and try out a CS9, Small Clone, Rocktron Tsunami, and of cause both the CE-2 and CE-3.
Its important to have references when doing so.
If possible, always have an a/b comparison.
Choose places that have a variety of choruses so you can place them side by side.
I can tell you - I never thought the CE-2 was a warm sounding chorus till I had the opportunity to try it beside other choruses. All I had before was review and words - praising its "warmth" but I just never really understood it.
And if you want to nail a tone from some song/album - look up the guy's gear. Easiest way about it. If any part of the gear equation is hard to get/rare/discontinued/too expensive, then just fill in as many blanks as possible, and go do your a/b.
