Mah and Binik have an excellent survey paper on the research related to human orgasm. Section 1.3.2 is dedicated to comparing the experiences of male vs. female orgasms. While they report that most studies conclude that there is more variance in the qualitative experience of female orgasm, it is also claimed that
...the scant research comparing male and female orgasm experiences demonstrates striking similarity between male and female accounts and suggests that male orgasm experiences are not completely determined by ejaculatory events. In the studies of Vance and Wagner (1976) and Proctor, Wagner, and Butler (1973), medical students, obstetrician–gynecologists, and psychologists were unable to differentiate between descriptions of orgasm written by male and female students.

As far as duration, the physical effects actually appear to be longer in men:
Average contractile duration was 16.7 seconds in females and 25 seconds in males (cf. [Bohlen et al., 1980], [Bohlen et al., 1982] and [Carmichael et al., 1994]).
however, it should be noted that the neurochemical and hormonal effects (which are much harder to measure) may have different durations.
As far as whether or not women are more prone to having multiple orgasms, that is still a somewhat open question. It is clear that women are quite capable of multiple orgasm, however, there is still variance. Men have been observed to have multiple orgasms (even in the laboratory), however, there are not enough studies yet to make any conclusions about its prevalence. Furthermore, there is not even an accepted definition for what constitutes "multiple orgasm". From the survey:
The biological capacity for multiple orgasm in women appears to be upheld, though there are individual differences ( [Masters & Johnson, 1966] and [Sherfey, 1972]; cf. [Amberson & Hoon, 1985], [Bohlen et al., 1982], [Darling et al., 1991] and [Hite, 1976]). While male orgasm is usually followed by a refractory period, male multiple orgasm with and without ejaculation has been described in a few uncontrolled self-report studies [Dunn & Trost, 1989], [Hite, 1981] and [Robbins & Jensen, 1978]. Kinsey et al. (1948) reported the occurrence of multiple orgasm in just over 55% of pre-adolescent males but in substantially fewer adult males, about 3% of men over the age of 30. Male multiple orgasm was reportedly observed in one laboratory study (Robbins & Jensen, 1978), but only a single subject was involved, and results were difficult to interpret. Operational definitions of multiple orgasm vary greatly [Amberson & Hoon, 1985], [Dunn & Trost, 1989] and [Robbins & Jensen, 1978], and so interpretations about findings are difficult to make.

better
is subjective butpowerful
isnt? Is there some measure of power we should be using? At very least power is relative, and if so what are we ralating it to? A Mans orgasm? Back to a reliable measurement of power.
