I've got a Motorola, Moto G (3rd Generation), I think they're up to 5th Generation now. It does have a very good camera and like you I use it mainly for texting/Whatsapp and occasional 'phone calls. It does have a couple of anomalies compared to other android 'phones, for instance you can't download your own music to use as a ring tone but that's not a problem unless you really wanted a particular piece of music.
One of my sons and his wife have always had Motorola Moto G 'phones, my son has recently bought himself the latest version.
Which? has an update on mobile 'phones this month, it had 3 best buys, a Samsung Galaxy Note 8 @ £869, a OnePlus 5T @ £449 and a Motorola Moto G5 Plus @ £200. About the Motorola it states "Our cheapest Best Buy has a 5.2 inch display. It's terrific value, with good photos and videos, 11 hours of web browsing from a single charge, and a fingerprint sensor".
I rarely browse the web on my 'phone - I use my laptop for that - and I usually re-charge my 'phone every 2-3 days, more if I've taken photos and videos of course.
