First off, I've never played through an Aguilar regularly, so I won't be any help answering that question.
My first gigging setup was a Clarus 1 and a Bergantino HT112 and a sans amp preamp in NYC.
A great lightweight setup with a built in direct setup for the boards. For both upright and electric.
The older Clarus, to answer the OP's question, for me was bulletproof, with only one issue over many years of use that I had to send it in for.
I graduated to a WW Blue light, and for the same travel weight, the sound was certainly a Toyota to Telsa like experience as J. Condino described above.
The difference was mostly in the voicing and strength of Walter's EQ for coloration and power of course, which adds substance and presence to the sound.
I was also playing an Alembic series one at the time when I gigged with an electric, so that married with the muscle of the blue light and the clarity and punch of the Berg, was hard to beat.
That said, the AI and the Berg with a sans amp preamp was really, really good and the Alembic provided enough power from the active pickups to give the blue light some competition.
I also had great service experiences from AI and Walter for both amps, with free shipping from both and great conversation to boot.
I had something of a gear purge over the last few years and decided to go with a double shot and a Clarus SL-2 along with the same sans amp preamp from years ago.
The setup is even lighter than my old berg setup and while it doesn't have the full import of the blue light which I sold during the sell off, I'm pretty happy with the results.
Rick Jones's amps are clean, powerful, and you really hear what your instrument really sounds like. Really great engineering there from people who know bass players, though I use the AI amps for everything, guitar, keyboard, etc because the clarity is just that good.
Walter's amps have their own mojo and are special as they are made by one creative genius by hand with great care for a specific purpose.
I also used the blue light with guitar for jazz as well, but for me it was all about how it sounded with the bass.
I do miss my blue light from time to time and may grab one again at some point, but my current AI setup is very enjoyable to play through and takes up a fraction of the space at home.
The only other thing I'd like to add is I was more nervous carrying the WW into a club situation as I feared a bit for it's safety because of the cost and rarity.
My current AI setup isn't inexpensive by any means, but knowing service is just an easy phone call away does provide confidence with using the platform.
Both great pieces of equipment that I've had the chance to play through over long periods.
If you have the opportunity to play through each of them with your instrument the way you like it setup, it would be very fun to do it.
I tried playing with both speakers and with the internal speaker disconnected. The change in volume was barely noticeable. The tone through the HT112 was different but still great. And really loud. The wattage rating of the AI amps is not exaggerated.
