Narrative: Noise abatement climb out of SNA. Clearance (CPDLC) FINZZ1 departure MISEN KEPEC arrival to LAS. Climb via SID except maintain 5000 ft. Passing through 4000 ft SoCal issued climb to 8000 ft climb via the SID. I read back the clearance and set the altitude alerter to 8000. I looked down at the SID and saw the crossing restriction at STREL at or below 5000 ft. Called out to PF the STREL restriction as we are passing 6500 ft. PF stated that we were cleared to 8000 ft. SOCAL called with a heading change and frequency change and [asked] were we aware of the 5000 ft crossing restriction. I called back that we believed we were cleared to 8000 ft. Controller then restated the frequency change.I believe that there were two factors that applied here. First; the clearance to climb to 8000 ft before we reached the 5000 ft hold down as we were in a rapid climb for noise abatement. To be clearer; I think the call should have been 'After STREL climb to 8000 ft climb via the SID.' Second the crew should have been more familiar with the 5000 ft crossing restriction and made sure we are climbing in VNAV. Also we should have made sure as a crew what the clearance actually was.Interesting side bar: Today we did the same SID with the same restriction of 5000 ft. SoCal cleared us to 8000 ft at exactly the same spot. I asked the Controller if we were cleared to climb to 8000 ft or were we to climb via the SID. He came back with we were indeed cleared to climb to 8000 ft at this time. Sometimes these RNAV SIDS can be confusing when we are issued exceptions to what we see on the SID we are issued and then then Controller changes things in a high workload environment.


Second narrative: Departing SNA on FINZZ1 departure. 5000 ft preselected in altitude window. This is the hold down at STREL. Prior to reaching STREL the Controller advised; cleared to 8000 ft. Climb via SID. The next fix at DOLLF has an 8000 foot restriction. Even by adding the phrase 'climb via the SID' we were both under the impression that the 5000 foot restriction was deleted. The other issue here is the quiet flying sensors all around the airport and everyone believes climbing up and out is preferred. This is a setup that needs serious attention. This was a no harm no foul day; no conflicting traffic.


Synopsis: G550 flight crew reported they overshot the 5;000 restriction at STREL departing SNA citing confusion with the 'climb via' clearance.
