Would love to know of the best option out there besides TiVo. Any ideas?
'Best option' is somewhat vague. How are you using it now? Cable? Off air?
For ease of use and locally stored content, I don't think there's anything. There are lots of techy-type solutions like Silicone Dust hardware, and YouTubeTV offers a 'cloud vcr' as does Plex. YouTube's has 'unlimited storage'.
When my Roamio dies, I'll be sorry to see TiVo go after about 20 years as a customer, but to replace it with another similar box is too much money for too little return. Also, while the quality of streaming video/audio has gone up and up over the last decade, the quality of the images delivered by Spectrum Cable has gone down consistently year after year as they increase compression to accommodate more channels on a single piece of coax and continue to use the 20 year old horrendous MPEG codec for compression and 5.1 audio (at best). And then there's the required Tuning Adapters and the fact that Spectrum is sending more and more channels onto their SDV system so the TA is required, and it misbehaves regularly. And yes, I know some systems don't need a TA. Spectrum does.
Especially now with a minimal amount of decent-to-adequate new episodic content being generated for cable, I find myself streaming using my AppleTV4K more and more, and watching properly compressed 4K wide color space Dolby Vision images with Dolby Atmos audio is light years ahead in terms of quality of anything my Spectrum cable system/TiVo combo spews out, which continues to be compressed to death 1080i or 720p MPEG video and 5.1 audio. Even the premium channels like HBO never get above 10 Mb/s, which would be fine with H.264, but with MPEG that is complete garbage on scenes where the actors or camera actually, you know, move.
