Reboots vs Extended Continuity
Of all the series cited as reboots only Enterprise can really be considered such.
TNG was explicitly a continuation of the timeline, not a reset nor did did it rely on any reset. DS9 and Voyager were also set in that same timeline (excluding those episodes in each of those series that deviated from that timeline for the purposes of weaving in an alternate timeline for unavoidable continuity preservation).
Enterprise, being set before TOS was (more) arguably a reboot for the simple reason that it was difficult to conceive that the technology presented in that earlier timeframe would or could "evolve" to the technology presented in TOS (in a way that was not so problematic for TNG and "later" vs TOS) even if strictly speaking we were supposed to accept that this is precisely what had in fact happened.
